Abstract

A successive structural analysis using wavelet is proposed to remove the block artifacts associated with block-based coding such as JPEG. The analysis is based on the different responses of block boundaries (constrained by quantization), and the structural information about an image in wavelet domain. In particular, information about an image is divided into a few bands according to their responses in wavelet domain. A metric is then proposed to quantify the quality of information in each band. As simulation results show, block artifacts are removed effectively by the proposed algorithm.
