Abstract

In the context of image coding, a number of reversible integer-to-integer wavelet transforms are compared on the basis of their lossy compression performance, lossless compression performance, and computational complexity. Of the transforms considered, several were found to perform particularly well, with the best choice for a given application depending on the relative importance of the preceding criteria. Reversible integer-to-integer versions of numerous transforms are also compared to their conventional counterparts for lossy compression. At low bit rates, reversible integer-to-integer and conventional versions of transforms were found to often yield reconstructed images with comparable quality, both subjectively and objectively
