Today massive video data transfers are successfully done over the Internet. But, achieving a good quality real time video Transfer is still a challenge. Video requires large bandwidth for error-free transmission over the network. Since bandwidth is an expensive resource, ensuring sufficient bandwidth for error free transmission of video is difficult. Hence, low bit rate transmission is preferred. But low bit rate transmission implies lower quality video. This is where Region of Interest Video Coding comes into play. It uses the fact that there are certain areas in the video which are of higher perceptual importance than other areas and assigns a higher quality to those areas. Hence a better perceptual video quality is achieved under the same bandwidth conditions.Region of Interest Coding can be broken into 2 parts: Region of Interest Tracking and Video Preprocessing. Region of Interest Tracking involves tracking the region of interest in all the frames of the video based on some criteria specified by the user. Video Preprocessing is the preprocessing performed, to ensure higher quality to the region of interest over the background. This thesis presents a methodology for both Region of Interest Tracking and Video preprocessing. In Region of Interest Tracking,a covariance tracking method is studied and is applied in the 2 different cases of rigid and non rigid body motion of the Region of Interest (ROI). In Video preprocessing, a spatio-temporal preprocessing technique is studied and is tested on different standard video sequences.
