一般注記This paper proposes a new efficient fractal coding scheme for video sequences and demonstrates its computer simulation results. The proposed scheme combines fractal coding with motion compensation (MC) prediction and sub-band decomposition. MC prediction with variable MC block size is carried out for an input video sequence. An MC prediction error image is divided into 7 sub-band images. The fractal block coding with adaptive range block size is performed only for the lowest frequency sub-band image. On the other hand, scalar quantization and entropy coding are carried out for the other 6 sub-band images. The computer simulation results show that the proposed coding scheme attains higher SNR (Signal-to-Noise Ratio) values and better reconstructed image qualities compared to the conventional fractal block coding scheme and MPEG1 scheme.
