Algorithm Development and Theoretical Methods for Coding Wavelet Transforms
Abstract
This report covers algorithm development and theoretical work. The reporters continued our investigation of correlation methods for coding images and began to investigate wavelet transforms. The work included six areas of interest: (1) Lossless compression; (2) Alternative tile classification schemes; (3) Elimination of compression artifacts; (4) Effects of image size on fidelity and compression; (5) Image preprocessing; and (6) Methods to improve tiling fidelity. While the compression ratios attainable with lossless compression schemes are far lower than those obtained with lossy schemes, the utility of lossless schemes is higher for many applications. We investigated briefly the idea of compressing the difference between an original image and a highly compressed version of the image.
