Abstract
The paper presents a pyramid coding technique for compression of halftone images. The image is divided into disjoint blocks. Each block is represented by a tree structured pyramid whose leaves are “uniform” areas defined to contain only the bit patterns that are possibly generated by single grey levels. The algorithm shows a high compression ratio in the experiments. The progressive transmission based on the algorithm allows an approximate image to be built up at a very low bit rate, and the details to be added gradually, which is useful for picture-browsing.
