Abstract

A K-th order adaptive transform coding algorithm is introduced to achieve a better tradeoff between the bi-trate and the image quality. This scheme first discriminates the image contents, based on the variations of the human visual degradation sensitivity on arious contents, and the appropriate parameters are then chosen accordingly. Some simulation results are given to illustrate the performance of this adaptive scheme. It is demonstrated that better image quality can be achieved with lower bitrate with this adaptive algorithm
