Abstract:

The research program is designed to accomplish two primary objectives 1 to obtain a basic understanding of the digital encoding process and to derive an optimum digital encoding algorithm under certain general conditions, and 2 to determine explicitly what kinds of practical digital encoding equipment should be used for the various tasks which require it. In order to accomplish these objectives, five working groups were formed and progress is reported herein in each of these groups -- source encoding theory, speech encoding, video encoding, pattern recognition and computer simulation.
