Application of wavelet-cosine transform to image compression

Abstract

A two-dimensional discrete transform which is a composition of the wavelet and the cosine transform is presented and applied to image compression. The usefulness of the 2-D wavelet and wavelet-cosine transform for the lossy compression is compared. Independently of which transform was used, the nonuniform quantization distinctly increased the efficiency of lossy compression.
