Abstract
A method and apparatus are presented for performing wavelet transforms, post transform processing and inverse wavelet transforms whereby hardware complexity is reduced and processor performance is enhanced by performing the forward and inverse wavelet transformations and post transform processing in variable precision arithmetic. Optimal decreases in the operational arithmetic precision of different wavelet scale coefficients, multiplication and weighting operations, and other operations, results in reduced computational complexity, increased speed, and in some cases better signal to noise ratios.
