Abstract :
A video coding method is proposed which is based on 3-D subband decomposition and adaptive selection of small blocks in each subband. The influence of energy threshold and block size on the coding performance is discussed. Simulation results have shown very good visual quality at 9 Mbit/s for test sequences of CCIR 601 format
