Abstract

An intra-prediction mode-decision method was proposed. Based on the inherent spatial correlation within a single frame and temporal correlation between successive frames

part of intra-prediction modes were chosen to determine the best prediction mode for image block

which resulted in directly reducing the computational complexity and maintaining high coding efficiency. In addition

a complexity-scalable technique was presented to control the complexity of intra prediction

by which the video coder was matched to the limited computational resource of communication equipments. The proposed methods are verified in AVS-M software platform.
