FIXED OR ADAPTIVE DEINTERLEAVED TRANSFORM CODING FOR IMAGE CODING AND INTRA CODING OF VIDEO

摘要

A coding strategy efficiently codes intra (macroblocks, regions, pictures, VOP) data. This strategy uses two basis approaches, a Fixed Deinterleaved Transform Coding approach, and an Adaptive Deinterleaved Transform Coding approach. Furthermore, within each approach, two types of coders are develop ed. One coder operates on an entire picture or VOPs and the other coder operates on small local regions. Using coders and decoders of the present invention, eff icient coding at a range of complexities becomes possible, allowing suitable tradeo ffs for a variety of applications.
