Abstract
The authors discuss a hybrid pyramid coding scheme for image data compression that is based on two coding techniques: subband pyramid and Laplacian pyramid. Source data are first decomposed into seven bands by subband pyramid coding. Only the lowest band is further decomposed by the Laplacian pyramid technique to reduce correlations between pixels. The advantages of the hybrid pyramid scheme are its efficiency and compactness. In the coding process, each component is PCM coded. The computer simulation results show that the quality of the reconstructed image is good up to a compression ratio of 10:1.>
