Abstract: A new class of block transforms is presented. These transforms are constructed from subband decomposition filter banks corresponding to regular wavelets. New transforms are compared to the discrete cosine transform (DCT). Image coding schemes that use the block wavelet transform (BWT) are developed. BWT's can be implemented by fast (O(N log N)) algorithms.<>
