Abstract
An data compression technique combines the benefits of block-wise processing, such as allows reduced buffer memory usage and improved speed through parallel techniques, with tree-type compression normally associated with wavelet-type compression techniques. Block artifacts in the reconstructed data at the partitions between blocks are minimized by use of lapping transformations.
