Moving image sequence coding using recursive binary nesting

Abstract

The quadtree-based interpolative recursive binary nesting technique is described, and methods of converting the algorithm from one used to code still pictures into one suitable for moving sequences at 64 kb/s are outlined. The implications of various forms of block testing, quantization, and motion compensation are discussed and compared, and areas requiring further work are noted. It is shown that the disturbing effects that are produced by using the original algorithm for moving sequence coding can be overcome and that motion compensation can be effectively applied to the coding procedure. A flow diagram of the complete system is included.<>
