Signs and symptoms
Classification of Pancreatic cysts using
Image Processing techniques.
What is a cyst?
A cyst is a closed sac having a distinct membrane and
division on the nearby tissue. They may contain air,
fluids, or semi-solid material.
Pancreas is a large gland that produces digestive
enzymes and hormones.
Pancreas can become home to many types of cystic
growths, some cancerous and some benign.
Appropriate treatment differs depending on the type of
cyst and whether it causes symptoms.
Signs and Symptoms
Persistent abdominal pain
A mass in the upper abdomen
Nausea and vomiting
Magnetic resonance imaging
Intraductal papilliary mucinous neoplasms
Image processing techniques such as edge
detection and thresholding are used to classify
the images of Pancreatic cysts
Thresholding was found to be more effective
than edge detection in classification
