Abstract

Subband image coding techniques have received considerable attention as a powerful source coding ones. These techniques provide good compression results, and also can be extended for progressive transmission and multiresolution analysis. In this paper, we propose a hybrid subband image coding scheme using DWT (discrete wavelet transform), DPCM (differential pulse code modulation), and ADPCM (adaptive DPCM). This scheme produces both simple, but significant, image compression and transmission coding.
