Comes to fitness, many people will be undaunted, is not reluctant to exercise, but no time. It seems to have is the unity of the majority of those who did not exercise reason. Then we too busy or insufficient time to really give up the gym, give up exercise the right, could not be more simple exercise methods, let a few minutes to exercise it?

The novel H.264/AVC video coding standard introduces many improvements in inter-frame motion.-
compensated prediction, although significantly increasing the computational complexity of the motion
estimation process. In this paper, we propose a fast-block based predictive-recursive motion estimation
algorithm, which applies two consecutive search steps, achieving same image quality of the classical
Full-Search Block Matching by using only 3% of the computation. Furthermore, the output of the first
search step can be used for efficient-on-the fly detection of scene changes in the video sequence, and
interlaced or progressive coding decision for each picture.
