Local visual perceptual clues and its use in videophone rate control

We present a method for extracting local visual perceptual clues and its application for rate control of videophone, in order to ensure the scarce bits to be assigned for maximum perceptual coding quality. The optimum quantization step is determined with the rate-distortion model considering the loc...
