The XYZ algorithm for real-time compression of full-motion video

In this paper, we describe a new full-motion video compression algorithm, based on three-dimensional Discrete Cosine Transform, The algorithm, called XYZ-video compression, takes advantage of statistical behaviour of video data both in spatial and temporal domains, We demonstrate the algorithm by implementing it in software and comparing it with the MPEG video compression standard, The results show a significant superiority of the proposed XYZ-video compression algorithm compared to the MPEG standard, This superiority is shown in several key categories: (i) XYZ-video compression gives much higher compression ratios than the MPEG standard for the same quality of the decompressed video, and (ii) the compression time for XYZ algorithm is much shorter than for the MPEG standard, This suggests that the XYZ-video compression scheme can be efficiently applied for real-time video compression.
