Abstract:
Algorithm for Video Data Compression Based on Improved Moving Picture Experts Group
Efficient compression of image sequence data is a limiting technology for many digital
video transmission and storage systems. Emerging video compression techniques such
as those based on the preliminary moving picture experts group (MPEG) standard cannot
consistently achieve maximum performance because they utilize fixed image partitions
and simple motion compensation algorithms. Significantly higher compression ratios
will be obtained by using the video compression approach based on adaptive sub-pixel
motion prediction and multi-resolution image representations. These enhancements
result in two-fold or greater reductions in the number of bits required to encode
the prediction error and the motion description--the two major components of the
MPEG inter-frame transmission. Phase I will integrate sub-pixel motion prediction
and multi-resolution descriptions within the framework of the emerging MPEG video
compression protocol, and will develop a software tool for off-line testing on actual
video data. Phase II will refine and select a final set of video compression algorithms,
and investigate their implementation in special-purpose VLSI hardware.
There would be markets in digital high-definition television, video conferencing,
video telephone, video training, video surveillance, video games, and video archiving.
