Description: 小波变换源码，国外VC开发的，效果比较好
I ve been involved with wavelet-analysis since my Ph.D studies and over the years developed various wavelet-transforms C++ libraries. This one concerns 2D implementation of the Fast wavelet transform (FWT). The 2D FWT is used in image processing tasks like image compression, denoising and fast scaling. I intended to design the implementation of the 2D FWT with custom filter support and simple in usage. I ve equipped it with known filter families: Daubechies, Coiflets and Biorthogonal wavelets. The wavelets used in compression tasks are Bior53 and Bior97. With Daub1 filter you can achieve fast dyadic image scaling algorithm. You may also experiment with other filters for compression and denoising and compare the results, you may also add your custom wavelets. The nice feature of this library is that reconstruction FWT filters are rearranged the way that you perform just convolution operations on the spectrum, which is very important if you d like MMX -err

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: 针对图像配准中常出现的RST(旋转-比例-平移)变换，推导出了相应的盒距离变换公式。与传统的基于广
义仿射变换的Hausdorff盒距离变换公式相比，缩小了搜索距离空间。在计算Voronoi表面时，根据Hausdorff距
离的计算需要提出比较滑动窗口的区域Voronoi表面，节省了计算Voronoi表面的时间。并且在利用边缘点计算
Hausdorff距离时，剔除琐碎的边缘，仅使用较长的边缘计算。试验结果表明，这些改进方法较大地提高了基于
Hausdorff距离的图像配准的计算速度。
-For image registration often appears RST (rotation- the ratio of- translation) transform, derived from the corresponding transformation formula box. With the traditional affine transform based on generalized distance transform of the Hausdorff formula box compared to the distance to narrow the search space. Voronoi surface in the calculation, according to the calculation of Hausdorff distance sliding window need to compare the regional Voronoi surface Voronoi surface is calculated to save time. Edge points and the calculation in the use of Hausdorff distance, remove the edge of trivial, only the edge of a longer calculation. Test results show that the method greatly improved Hausdorff distance-based image registration of the computing speed.
