Predictive Motion Estimation for Reduced-Resolution Video from High-Resolution Compressed Video
To convert a compressed video sequence to a lowerresolution compressed video, one typically needs to decompress the original sequence, down-sample each frame, and recompress it. It involves motion estimation in the reduced sequence which is computational intensive. In this paper, we propose a novel fast algorithm to predict the motion vector of the reduced video by using the original motion information in the compressed bitstream. We achieve a much higher quality than existing algorithms with low additional complexity.
