Abstract

In this paper, we investigate transform quantization scheme for exploiting motion masking effect (MME). The study is carried out by adapting the quantizer with respect to the movement of the image. The idea of the strategy is based on a velocity dependent HVS model. Through simulation, motion adaptive quantization (MAQ) is proved effective with intra field coding. A scheme of a motion compensated DCT coding with MAQ is then presented. Technical points essential to its realization are explained.
