Mei Shen, Chong Siew Tan, Lucas C. K. Hui, Pte Ltd · 1993
An adaptive DCT/NON-DCT is presented, and applied to video edge coding --Lossy coding (high compression) and lossless coding system. It is found that Non-DCT method used here can improve picture quality and reduce the ringing distortion around edges, and realize lossless coding successfully.
