Paper Abstract

A hybrid algorithm for high rate image compression based on spline wavelet packets and vector quantization is presented in this paper. The algorithm consists of (1) a fast projection of an image signal onto the spline-wavelet space, (2) an efficient spline-wavelet packet decomposition algorithm, (3) a method to select the optimal number of component subimages, (4) criteria for thresholdings, and (5) vector quantization of subimages. We have compressed a test image to 0.08 bpp from 8 bpp with PSNR of 27 db.
