Parameter Optimization for Delayed-Decision Pattern-Matching Image Coding

Abstract

The previously developed universal pattern-matching coding technique(PCM) uses different coding modes, and adaptively chooses the proper coding mode instantaneously for a given input subblock. To improve the adaptability of the coding mode selection, we introduced the delayed-decision mechanism with the (M, L) algorithm. The work presented here optimizes the values of its search parameters from the standpoint of the coding performance.
