Description: 由于小波变换转换过程中出现浮点数,使得256*256的图像压缩后不能为128*128.采用小波提升算法可以解决这个问题,由于小波提升算法可以实现整数到整数的变换,且可以完全重构信号.并且采用提升算法可以提高算法执行的速度.-Wavelet transform as a result of the conversion process appear in floating-point numbers, making the image 256* 256 can not be compressed to 128* 128. Wavelet lifting scheme can solve this problem, as the wavelet lifting scheme can realize integer to integer transform, and can be completely remodeling signal. and using lifting scheme algorithm can improve the speed of implementation.

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.

Description: Quincunx wavelet transforms
Quincunx wavelets are non-separable transform that allows to avoid using vertical/horizontal wavelets. The scaling grows like 2^{j/2} with the scale j instead of 2^j, which can be advantageous.
Biorthogonal quincunx wavelets are implemented using a simple wrapper to the code of Dimitri Van De Ville.
Redundant, translation invariant transform are implemented with the lifting scheme.
