A Design of Adaptive Quantizer for MPEG-2 Video Coding
Based upon studying the strategy for adaptive quantization suggested by MPEG-2 Test Model 5,a new quantizer is presented in this paper.Block-based visual activities are analyzed to exploit local perceptual characteristics in the macroblock.In order to decide the adaptive perceptual quantization fact...
