Video Compression Algorithms for Transmission and Video.

摘要: Abstract : During the past year, we have continued our efforts in area of signal, image and video representation, compression, storage, transmission enhancement. In transmission, focused on optimal joint/source channel coding for noisy wireless channels. submitted very low bit rate algorithm to MPEG-4 standardization body into November 1995. Our matching pursuit performed among top 3 all submissions compression. also complexity, real time software codecs scalable video. Specifically, shown that by trading off compression efficiency with can achieve encode decode capability today's workstations. storage retrieval, placement Variable Bit Rate (VBR) parallel disk arrays developed new admission control strategies. These schemes were tested experimentally a system lab. resolution enhancement, novel motion estimation scheme multiframe Finally, circuits systems signal processing, oversampled data conversion systems, such as sigma delta modulators. analytical simulation techniques locating dominant tones double loop Sigma Delta A/D converters.
