A Novel Video Compression Approach Based on Underdetermined Blind Source Separation
This addresses video storage and transmission efficiency for multimedia applications, but it is incremental as it builds on standard codecs.
The paper tackles video compression by combining underdetermined blind source separation with existing codecs, achieving a 33% improvement with MPEG-2 and 4X-12X higher compression ratios with H.264 while maintaining acceptable PSNR.
This paper develops a new video compression approach based on underdetermined blind source separation. Underdetermined blind source separation, which can be used to efficiently enhance the video compression ratio, is combined with various off-the-shelf codecs in this paper. Combining with MPEG-2, video compression ratio could be improved slightly more than 33%. As for combing with H.264, 4X~12X more compression ratio could be achieved with acceptable PSNR, according to different kinds of video sequences.
