Abstract

We propose a two-layer sequence image coding algorithm based on residual block matching using fractal approximation. First, the motion compensation (MC) error signal is encoded by the discrete cosine transform (DCT). The motion vector and DCT coefficients are transmitted as the first layer and the residual signal of MC/DCT is encoded by fractal approximation and transmitted as the second layer. The second layer is encoded by the matching block selected from a dynamic residual pool. The reconstructed MC error image is used as a dynamic residual signal which is called a domain pool in conventional fractal coding. The computer simulation result by the proposed methods and the DCT-based methods shows that the performance improvement by the proposed method is significant.
