Paper Abstract

In this paper we make a comparison between wavelet transforms and the local cosine transform of various types of images. This builds on our previous work involving acoustic signals, where we found that the local cosine transform gave a more compact representation for certain types of signals and performed as well as wavelets for others. This held even for signals that were transient in nature, where one might expect the wavelets to do better. We are interested in determining if the same holds true for images, which tend to include many transients, such as edges. We are also investigating the extent to which the rms error can be used to evaluate the perceptual quality of the reconstructed images.
