This paper presents a novel hybrid multi-scale, perceptual and vector quantization based video coding scheme. In intra mode of operation, a wavelet transform is applied to the input frame and decorrelate it into a number of subbands. The lowest frequency subband is losslessly coded. The coefficient of the high frequency subbands are pixel quantized using(More)
In this paper a new hybrid multiresolution human visual system and statistically based image coding scheme is presented. It decorrelates the input image into a number of subbands using a lifting based wavelet transform and employs a novel statistically based coding algorithm to code the coefficients in the detail subbands. Perceptual weights are applied to(More)
