Abstract
Space domain image coding with VQ [9, 10, 11] has been very effective at low rates. To achieve quality at lower rates, it is necessary to exploit spaial redundancy over a larger region of pixels than is possible with general VQ. This paper presents a interframe coding algorithm which is capable of obtaining better performance and lower bi t rate than those of the general interframe coding. The performance is evaluated on the basis of SNR (Signal to Noise Ratio), memory requirements and bit rate.
