Design of three-channel filter banks for lossless image compression

Abstract

This paper proposes a novel design method for 3-channel filter banks based on the lifting scheme. The resulting filter bank is able to map integer signal values to integer sub-band values. The design also offers low-complexity handling of the signal boundaries. In application to image data compression, the new integer wavelet decomposition shows competitive performance compared to the reversible 5/3 transform used in JPEG2000.
