Abstract

Video compression is vital for efficient storage and transmission of digital video signal. The hybrid video coding techniques based on predicative and transform coding are adopted by many video-coding standards such as ISO MPEG-1/2 and ITU-T H.261/262/263, owing to its high compression efficiency. Motion compensation is a predictive technique for exploiting the temporal redundancy between successive frames of video sequence. Block matching is a simple and effective motion estimation method to obtain the motion compensation prediction. In panorama camera motion, we can enhance the bit rate and minimize the encoding time by calculating the largest block This minimizes the number of motion vectors required for P picture coding which improves the bit rate by average ratio 1:975, which is the ratio between the largest block and the equivalent blocks in the standard MPEG.
