Fast Training-Based Redundant Predictor Elimination Scheme for Intra Coding in H.264/AVC
Currently, Laroche et al. presented an efficient method to eliminate redundant predictors for intra coding in H.264/AVC. Their proposed method has a bitrate reduction advantage under a low bitrate environment. In this paper, we present a fast training-based redundant predictor elimination scheme to enhance the execution-time performance while preserving similar bitrates. We first develop a new statistic training approach to construct a set of most similar predictor-pairs and determine the priority of each predictor. Based on the constructed predictor-pair set and the determined predictor priorities, we thus can efficiently eliminate the redundant predictors and preserve more frequently used ones, leading to the advantages of bitrate reduction and computation-saving. The results of experiments on the twenty-one standard Video Coding Experts Group (VCEG) test sequences turn out that under similar bitrates, the average execution-time improvement ratio of the proposed method over Laroche et al.’s method can be more than 33.603％.
