Abstract :
In video communication applications, there are great demands of high-efficiently coding of video sequences. To improve subjective video quality, preferred ROT (Region of Interest) coding has widely been studied. In this paper, we employ the object coding techniques to encode ROT with higher priority. When we use the object coding to specify ROT, shape of the object does not require high accuracy. Therefore, we can improve the coding efficiency and reduce tracking difficulty by simplification of ROI shape.
