Abstract (EN): An algorithm for coding image sequences based on the segmentation of the differential image into variable size and variable shape blocks is described. The differential image is split into 4 × 4 blocks, that are grouped to form square and rectangular macro blocks of several areas. Each macro block is then vector quantised. Simulation results presented show that compression rates and subjective quality compare favourably with methods previously described.
