In this paper, we present preliminary results comparing the nature of the errors introduced by the mixture of principal components (MPC) model with a wavelet transform and the Karh...
A new approach of backward coding of wavelet trees (BCWT) is presented. Contrary to the common “forward” coding of wavelet trees from the highest level (lowest resolution), th...

A degree-k zerotree model is presented, in order to quantify the coding power of zerotrees in wavelet-based image coding. Based on the model, the coding behaviors of modern zerotr...
—Embedded zero-tree coding in wavelet domain has drawn a lot of attention to the image compression applications. Among noteworthy zero-tree algorithms is the SPIHT algorithm. For...
