Image Data Compression Method, Pattern Model Positioning Method In Image Processing, Image Processing Apparatus, Image Processing Program, And Computer Readable Recording Medium - Patent 8150213
S The present application claims foreign priority based on Japanese Patent Applications No. 2008-206479, filed Aug. 9, 2008, and No. 2008-267978, filed Oct. 16, 2008, the contents of which is incorporated herein by reference.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data compression method for an image to be searched, a pattern model positioning method in image processing, an image processing apparatus, an image processing program, and a computer readable recording mediumupon searching out of the image to be searched and positioning a pattern model corresponding to a pre-registered image. 2. Description of the Related Art An image processing apparatus for processing an image picked up by an image pickup element typically includes: an image pickup apparatus for picking up an image processing object (hereinafter also referred to as "work"); an image data storingdevice for storing data on the image picked up by the image pickup apparatus; and an image data processing device for processing the image data stored by the image data storing device. For example, in the image processing apparatus where the imagepickup apparatus is made up of a CCD camera, luminance data (so-called multi-valued data) such as 256 levels of gray or 1024 levels of gray is obtained based on each of charge amounts of a large number of charge coupled elements constituting an imagepickup surface, whereby a position, a rotational angle and the like of the work as an object to be searched can be found. Conventionally, as techniques for performing processing on image data to search an object to be searched in image processing, thereare known a difference search performed using a total value of absolute values of pixel difference values between images, a normalized correlation search performed using normalized correlation values between images, and the like. In these searches, anobject to be searched that is wished to be searched is previously registe
Systems And Method For Composite Elastography And Wave Imaging - Patent 8150128
The present invention relates to medical imaging, and in particular to increasing the frame rate of ultrasound imaging by dividing the field of view into sectors, obtaining a series of ultrasound images for each sector, synchronizing the imagesand combining them to form a composite high-frame rate image.BACKGROUND Ultrasound imaging can be a useful tool in cardiology, such as, for example, in the diagnosis of myocardial infarctions. Ultrasound imaging of the heart, known as echocardiography, can be used, for example, to derive strains, which are relatedto the contractility of the heart muscle. However, current methods of real-time raw data acquisition of a full view of the heart limit the data acquisition rate to 50 frames per second (fps). It is noted that a "full view" is actually the default sizeof an image plane in a given system, which can be defined by a spanned angle (i.e., arc length according to the center of an imaging probe) and a chosen depth (beam direction). Tracking rapid motion of the heart in a short period or depicting thehigh-speed electro-mechanical wave propagating in the heart at frame rates of 50 fps is difficult. Moreover, because strains involve motion of the heart muscle, a frame rate (effectively a sampling rate of the displacement function over time) isrequired to be high enough such that interframe motion is relatively small to be accurately estimated. Using conventional frame rates, strain image results tend to be both noisy and unreliable This is because the lower the frame rate, the lesscorrelated any two consecutive frames are, which makes radio-frequency (RF)-cross-correlation based motion estimation techniques less accurate. One quantitative measure of the noise on strain images is the elastographic signal-to-noise ratio, or SNRe. With the high frame-rate composite imaging, precise and detailed motion/strain estimates in full view can be obtained and further used to differentiate abnormal from the normal myocardium and even
Image Processing Apparatus And Method And Image Display Apparatus - Patent 8150198
1. Field of the Invention The present invention relates to an image processing apparatus, an image processing method, and an image display apparatus. In particular, it relates to methods of reducing the occurrence of false edges in a digital image by gray scaleinterpolation when the gray scale of a digital image is expanded by bit extension. 2. Description of the Related Art In recent years, the brightness of the display screens of television sets and monitors has been increasing. As brightness increases, the amount of change in brightness per gray level in the gray scale increases. Ten-bit liquid crystal panelsand other display devices with high gray-scale resolution are being developed, but digital television broadcasting uses an eight-bit gray scale, so despite the ten-bit resolution of the latest display devices, the effective resolution of the gray scalein a television picture remains eight bits. Not only does this prevent full utilization of the features of these new display devices; picture signals that should grade smoothly in color or brightness, such as pictures of a sunset or the surface of thesea, may instead grade in a staircase pattern, skipping one or more intermediate gray levels at each step and thereby producing visible false edges. When only one level is skipped, the false edge can be eliminated by an averaging process. To deal with jumps between two gray levels that differ by N levels, where N is any integer greater than one, Japanese Patent Application Publication No.10-84481 (Paras. 0002 to 0006 and 0025 to 0028, FIGS. 1 and 2) defines an interpolation region around the jump, separates the interpolation region into (N+1) discrete subregions, and assigns sequential gray levels to the subregions. A general problem of such methods is that they fail to distinguish between true image edges and false edges caused by bit extension. If used to smooth out false edges, these methods also smooth out real edges, leading to a loss of sharpness, as
Image Processing Apparatus, Image Processing Method, Program, And Data Configuration - Patent 8150205
CROSS REFERENCES TO RELATED APPLICATIONS The present invention contains subject matter related to Japanese Patent Application JP 2005-353027 filed in the Japanese Patent Office on Dec. 7, 2005, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus, an image processing method, a program, and a data configuration. More specifically, the present invention relates to an image processing apparatus, an image processing method, aprogram, and a data configuration capable of generating natural face images. 2. Description of the Related Art A technique of generating a face image of a different expression on the basis of a face image is called morphing (e.g., Patent Document 1: Japanese Unexamined Patent Application Publication No. 2001-175881). The morphing is a technique of generating images to complement an intermediate process (hereinafter referred to as intermediate images as necessary) in order to express a gradual change from an image P1 to another image P2 by animation (movingimages). The intermediate images are generated by variations of shapes of the images P1 and P2 and blending of the images P1 and P2 (blending of pixel values). In the morphing, for example, animation smoothly changing from an expressionless face to a smiling face can be realized by using an expressionless face image and a smiling face image of the same person. Also, in the morphing, animation smoothly changing from a human to an animal, animation smoothly changing from a child to an adult, and animation smoothly changing from a person to another person can be realized.SUMMARY OF THE INVENTION In the morphing, control points are set on the image P1 and control points corresponding to the control points on the image P1 are set on the image P2. An intermediate image is generated by smoothly moving the control points on the image P1 tothe positions of the corresponding
Inferred Discovery And Construction Of Multi-resolution Images - Patent 8150214
BACKGROUND Computer monitor resolution has increased along with computer network bandwidth. However, many images stored on processing devices connected to a computer network, such as, for example, the Internet or other networks, are not encoded in amulti-resolution format. Consequently, a user may execute a browser on a processing device to view an image not encoded in the multi-resolution format. As the user starts "zooming-in" on rendered content, including the image, the image may be renderedlarger than originally intended. As a result, the image may be rendered with poor detail and may become pixelated.SUMMARY This Summary is provided to introduce a selection of concepts in a simplified form that is further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subjectmatter, nor is it intended to be used to limit the scope of the claimed subject matter. In embodiments consistent with the subject matter of this disclosure, a method and a processing device may be provided. The processing device may execute a browser application for obtaining content from a specified address via a network andrendering the content to a display monitor of the processing device. The obtained content may include an image. The processing device may attempt to discover a second image, corresponding to the image included in the obtained content, but having aresolution different from a resolution of the image included in the obtained content. If the second image is discovered, then the image and the second image may be linked to create a multi-resolution image. A user may enter a command to enlarge an image included in the rendered content. As the image is enlarged, the enlarged image may become pixelated. The processing device may detect that a size of the enlarged image is beyond a threshold andmay attempt to discover a corresponding image having a higher resolution than the enlarged image. If t
Methods And Apparatus For Automated True Object-based Image Analysis And Retrieval - Patent 8150216
FIELD OF THEINVENTION This invention generally relates to query processing or search techniques for databases or files containing visual information or images. More specifically, the present invention is directed to an automated and extensible system for theanalysis and retrieval of images based on region-of-interest (ROI) analysis of one or more true objects depicted by an image.BACKGROUND ART The proliferation of digital images and video has been a direct result of more efficient methods for gathering digital imagery. From recording devices such as digital cameras and digital video recorders, to digitizers for CCTV and broadcastmedia, to 2-D home and office scanners for producing digitized versions of photographs, the myriad digital recording methods has created an explosion of digital media. For purposes of the present invention, the term "image" will signify a two-dimensional digital representation of a scene, typically created and digitized by an image capture device, signifying a standalone event or a momentary representation ofa sequence of events. The term "object" will refer to a uniquely identifiable physical thing or item at least partially depicted in an image. The term "content" will refer to the subject matter of an image. Along with the countless forms of digital imagery, many different methods have appeared that attempt to organize and structure the digital repositories in such a way that permit retrieval of images in a structured or semi-structured fashion. Unfortunately, providing some structure to the imagery requires conformance to a certain format, necessitates an input process that structures the information, or requires human interaction to annotate the imagery for later retrieval. The most popularexamples of image search engines, such as Alta Vista and Google, for example, rely exclusively on annotations and/or file names associated with the images as the only basis for determining whether that image contains desired visual information.
Moving Picture Coding Method And Moving Picture Decoding Method - Patent 8150180
The present invention relates to a moving picture coding method and a moving picture decoding method, and particularly to a coding method and a decoding method using inter-picture prediction with reference to previously coded pictures.BACKGROUND ART With the development of multimedia applications, it has become popular to handle integrally all kinds of media information such as video, audio and text. For that purpose, digitalization of all these kinds of media allows handling of them in anintegral manner. However, since digitized images have an enormous amount of data, image information compression techniques are absolutely essential for storage and transmission of such information. It is also important to standardize such compressiontechniques for interoperation of compressed image data. There exist international standards for image compression techniques, such as H.261 and H.263 standardized by International Telecommunication Union-Telecommunication Standardization Sector (ITU-T)and MPEG-1, MPEG-4 and others standardized by International Organization for Standardization (ISO). ITU is now working for standardization of H.26L as the latest standard for image coding. In coding of moving pictures, in general, information amount is compressed by reducing redundancies in both temporal and spatial directions. Therefore, in inter-picture prediction coding, which aims at reducing the temporal redundancy, motionof a current picture is estimated on a block-by-block basis with reference to preceding or subsequent pictures so as to create a predictive image, and then differential values between the obtained predictive images and the current picture are coded. Here, the term "picture" represents a single sheet of an image, and it represents a frame when used in a context of a progressive image, whereas it represents a frame or a field in a context of an interlaced image. The interlaced image here isa single frame that is made up of two fields having different times resp
Image Processing Apparatus, Method And Program - Patent 8150217
1. Field of the Invention The present invention relates to the reuse of an edited multiple viewpoint image. 2. Description of the Related Art According to Japanese Patent Application Laid-Open No. 2004-102513, an image for stereoscopic vision is generated by correcting an acquired parallax image for brightness, color difference and upper or lower position. According to Japanese Patent Application Laid-Open No. 2006-262202, the corrected history information of an image is recorded as additional information in a corrected image file. In producing a print or display output for stereoscopic vision from the image taken from plural viewpoints (multiple viewpoints) as in Japanese Patent Application Laid-Open No. 2004-102513, it is common to make correction and conversion for theimage optimal to an output system without directly outputting the taken image. In this conversion to the output system, it is required to make optimizations for not only the kind or type of apparatus in the output system, but also various conditions including the size of screen, appreciation distance and range (horizontalangle). The processing content of how an original parallax image is corrected to generate an image for stereoscopic vision is not known afterwards in Japanese Patent Application Laid-Open No. 2004-102513. It is difficult to reuse the results of correction made in the past, because the location of a file generated as a result of correction or what correction is made in the corrected file is not known in an original image file before correction inJapanese Patent Application Laid-Open No. 2006-262202.SUMMARY OF THE INVENTION Thus, it is an object of the invention to reuse the processing content according to an output system for the multiple viewpoint image. According to the present invention, there is provided an image processing apparatus comprising a master image acquisition part for acquiring a master image that is multiple viewpoint image data taken from two or more viewpoints,
Routable Image Pipeline Device - Patent 8150215
1. Field of Invention The present invention relates to an image pipeline, and more particularly to a routable image pipeline device. 2. Related Art In recent daily life, various digital technologies replacing conventional analog technology have become very popular, and among others, the digital image technology is a good example. In a digital image, values of pixels in the image arerecorded in an array form, and the value of each pixel in the image is represented by limited bits. For example, a digital camera captures an image with an optical sensor and converts the image into a digital signal, and a series of image processing is performed on the digital signal. The most common method for processing the digital image isto apply various filters to the digital image, for example, to process original mono color pixels of the digital image to RGB pixels and YUV pixels sequentially by using filters, or perform various digital image processing such as noise reduction, imagesharpening, image tone variation, image brightness variation, or edge detection on the digital image. In addition, in order to perform the step of digital image processing requiring a plurality of filters, image pipeline architecture emerges. The image pipeline connects the filters to be executed, and provides a line buffer corresponding toeach filter respectively, so as to store image pixels. However, the conventional image pipeline has the disadvantages that the line buffer lacks flexibility in use and it is inconvenient in modification and expansion. The length of the line buffer islimited by a scanning mode of accessing the digital image or the length of the digital image, and the number of the line buffers is limited by the size of the corresponding filters, for example, a 3.times.3 filter or a 7.times.7 filter. Further, thefilters used by the image pipeline are fixed, so the image pipeline can only be used for processing fixed digital images, and thus lacks expandability. Moreover, if th
Image Pickup Apparatus Having Stability Checker For Specific Object Feature Value, And Program And Method For Control Of Image Pickup Including Checking Stability Of Specific Objec - Patent 8150208
1. Field of the Invention The present invention relates to an image pickup apparatus, and a device and method for control of image pickup. More particularly, the present invention relates to an image pickup apparatus, and a device and method for control of image pickup,in which an object can be photographed in an optimized condition to obtain an image of high quality easily without need of high skill of a user. 2. Description Related to the Prior Art A digital still camera is known as an apparatus in which an object image is picked up by photoelectric conversion to record image data of the object image. Various functions are carried out in the digital still camera to pick up an image in anoptimized condition. U.S. Pat. Pub. 2005/219395 (corresponding to JP-A 2005-286940) has a construction of detecting a face of a person according to image data. When a face is detected, a frame for the face detection is indicated with a live image of the person. A portion of the image associated with the detection region is evaluated to carry out AF control (autofocus control) and AE control (auto exposure control). It is possible to photograph an image in an optimized focus and exposure even in a scene wherethe AF control and AE control are very difficult to utilize. JP-A 2005-284203 discloses a digital still camera in which a focus lens is moved to pick up an image. A face is detected according to image data of respective lens positions. A face feature value of the face is also determined, for imagepickup by setting the focus lens in a position where the face feature value is maximized. JP-A 2004-135029 and 2005-045600 disclose a digital still camera in which plural image data of different focus positions are obtained by focus bracket photography. One of the image data with a highest focus evaluation value is automaticallyselected, and stored as a recorded image. JP-A 2005-045601 discloses a digital still camera in which a portion of a person is extracted before image
System And Method For Automatic Digital Image Orientation Detection - Patent 8150212
1. Field of the Invention This invention generally relates to digital image analysis and more specifically to automatic digital image orientation detection. 2. Description of the Related Art Substantial current multimedia analysis research focuses on information retrieval of digital content. However, the huge body of content-based image processing and understanding techniques are based on the assumption that the input images arecorrectly oriented. Though mechanical sensors can produce meta data indicative of the correct orientation when the image is produced, the lower-end digital cameras, cell-phone cameras and scanned images still require for the user to manually provide thecorrect orientation. As an indispensable component of photo management tasks, this orientation assignment will surely benefit from automation. There is a significant body of related work in image orientation classification. This work can be roughly grouped into methods that use only low-level features or those that additionally incorporate high-level semantics. Much of the mostrecent work has argued that further improvements in this problem will require deeper semantic image analysis at the level of object recognition. Many others adopt the low-level feature based only approach. Among the first few explorations, work described in Aditya Vailaya, HongJiang Zhang, Changjiang Yang, Feng-I Liu, and Anil K. Jain, Automatic image orientation detection. IEEE Transactions on Image Processing, 11(7):746-755, 2002, compared anumber of standard classification methods for image orientation classification, including SVMs and nearest neighbors. The authors of the above work used the Corel image dataset and presented a Bayesian approach to incorporate priors for the orientationclasses. Dimension reduction using minimum description length selects the subspace dimensionality. The method that the authors felt provides the best combined efficiency and performance used a learning vector quantizer (LVQ
Liquid-crystal-driving Image Processing Circuit, Liquid-crystal-driving Image Processing Method, And Liquid Crystal Display Apparatus - Patent 8150203
The present invention relates to a liquid crystal display apparatus, and more particularly to an image processing circuit and image processing method for driving a liquid crystal so as to improve the response speed of the liquid crystal.BACKGROUND ART Liquid crystal panels are thin and lightweight, so they are widely used in display apparatus such as the display units of television receivers, computers, and mobile information terminals. However, they have the drawback of being incapable ofdealing with rapidly changing moving pictures, because after application of a driving voltage, it takes some time for the desired transmittance to be reached. To solve this problem, a driving method that applies an excess voltage to the liquid crystalwhen the gray-scale value changes from frame to frame, so that the liquid crystal reaches the desired transmittance within one frame, is adopted in Japanese Patent No. 2616652. More specifically, the image data of the current frame are compared pixel bypixel with the image data one frame before, and when there is a change in the gray-scale value, a correction corresponding to the change is added to the image data of the current frame. When the gray-scale values increases in comparison with thepreceding frame, a driving voltage higher than the normal driving voltage is thereby applied to the liquid crystal panel; when the gray-scale value decreases, a driving voltage lower than the normal driving voltage is applied. To practice the above method, it is necessary to have a frame memory from which to output the image data of the preceding frame. With the increasing numbers of pixels displayed on today's large liquid crystal panels, it becomes necessary tohave an increasingly large frame memory. As the number of pixels increases, the amount of data that must be written into and read from the frame memory within a given time (within one frame interval, for example) also increases, so the frequency of theclock that controls the reading
Image Processing Apparatus, Method, And Computer Program With Pixel Brightness-change Detection And Value Correction - Patent 8150201
CROSS REFERENCES TO RELATED APPLICATIONS The present invention contains subject matter related to Japanese Patent Application JP 2007-059972 filed in the Japanese Patent Office on Mar. 9, 2007, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus, an imaging apparatus, and an image processing method, and a computer program. Specifically, the present invention relates to an image processing apparatus, an imaging apparatus, animage processing method, and a computer program in which a high-quality output image is generated on the basis of two types of images, that is, a long-time exposure image and a short-time exposure image. 2. Description of the Related Art Solid-state imaging elements such as a charge-coupled device (CCD) image sensor and a complementary metal oxide semiconductor (CMOS) image sensor used in video cameras, digital still cameras, and the like accumulate electric charge correspondingto an amount of light incident thereon, and output an electrical signal corresponding to the accumulated electric charge, in other words, performs photoelectric conversion. However, there is a limit to the amount of electric charge that can beaccumulated in photoelectric conversion elements. When an amount of light more than a certain level is received, the amount of accumulated electric charge reaches a saturation level so that a subject area brighter than a certain value is set to a levelof saturated brightness. That is, a "white-out" problem occurs. To avoid such a white-out phenomenon, a period during which electric charge is accumulated in a photoelectric conversion element is controlled in accordance with a change in ambient light or the like to adjust exposure time to optimally controlsensitivity. For example, when a bright subject is photographed, a shutter is released at a high speed to reduce the exposure time to reduce the per
Image Synthesis System For A Vehicle And The Manufacturing Method Thereof - Patent 8150210
The present invention relates to an image synthesis system for a vehicle. More particularly, it relates to a system which is disposed on a vehicle to provide the driver a downward-facing image of the vehicle's 360.degree. surrounding view tomonitor the periphery of the vehicle.BACKGROUND OF THE INVENTION A blind spot problem threatens the driver's safety, especially when driving a vehicle in complicated environments such as narrow alleys and parking lots. To ease this problem, one can mount a rear-view camera on the back of the vehicle for thedriver being able to see the back while backing up. However, it is difficult for the driver to simultaneously monitor four sides of the vehicle and thus the potential risk of an accident is high. U.S. Pat. No. 7,139,412 applied by Nissan disclosed a car surveillance system which comprises: mounting several cameras on a vehicle, shooting the images of the periphery of said vehicle, synthesizing all the images into one image anddisplaying said image on a screen installed in the car. However, if there is a 3D object presenting on the seams of the synthesized images, the edges of the object in one image will misalign to the edges in the other image, so that the systems can'tprovide accurate image data for the driver. In view of the disadvantages, the present invention provides an image synthesis system for a vehicle and the manufacturing method thereof which comprises: shooting the images of the periphery of a vehicle by the cameras disposed on said vehicle,synthesizing the images into a downward-facing image, stitching of two adjacent images in a smooth and seamless manner, and displaying a high quality synthesized image on a display device, to provide a better monitoring experience to the driver.SUMMARY OF THE INVENTION The present invention provides an image synthesis system for a vehicle and the manufacturing method thereof based on the problems stated above. One object of the present invention is to provide an image sy
Accelerating The Hough Transform - Patent 8150207
FIELD The present disclosure describes a method and apparatus for accelerating the Hough transform.BACKGROUND It may be desirable to detect lines, circles, ellipses and other geometries in digital and/or video images. Such geometries may be detected through a brute force method of analyzing every group of points (or pixels). For example, to detectlines, every pair of points or pixels may be analyzed to find groups of collinear or nearly collinear points. Such an approach is computationally intensive and may not be efficient. The Hough transform may be used to detect a line, circle, ellipsoid orother geometry in a video and/or digital image. The Hough transform may provide a more desirable method of detecting such geometries.
