查询词典 image compression

A new algorithm of low bit rate image compression was proposed. Firstly, the edge informations of the input image were detected with SUSAN operator, then the detected edge informations were en hanced with edge enhancement method. Finally, the enhanced edge informations were added to the decoded input image to form the final compressed image.
