Description: A collection of functions is presented which includes 2nd generation wavelet decomposition and reconstruction tools for images as well as functions for the computation of moment invariants. The wavelet schemes rely on the lifting scheme of Sweldens. Rectangular grids are split into quincunx grids, also known as red-black ordering. The prediction filters include Neville filters as well as a few nonlinear ones fairly capable of preserving local maxima or minima. The decomposition and reconstruction functions are called in the style of the Matlab Wavelet Toolbox. Many small and a few elaborate examples have been included, ranging from the
computation of moment invariants to
multiresolution image fusion. Please
see Contents.m for an exhaustive list.
