In order to achieve high compression ratios while maintaining high visual quality, this paper propose a new hybrid zerotree and DPCM based wavelet coding scheme for still image. We further exploit the dependencies between neighboring pixels in the same subband and the dependencies between descendants and ancestors in this paper, and we apply an explicit quantizer to each coefficient, then we transfer and encode data by bitplane progressively to maintain an embedded characteristic.
