matlab工具箱 图像的处理 强大 可以看看 函数多(matlab image processing toolbox function can look more powerful)

说明：  龚纯主编的“matlab语言常用算法程序集”的第九章源代码(Gong pure edited matlab language commonly used algorithm for assembly, &quot the ninth chapter of source code)

道格拉斯-普克算法(Douglas–Peucker algorithm，亦称为拉默-道格拉斯-普克算法、迭代适应点算法、分裂与合并算法)是将曲线近似表示为一系列点，并减少点的数量的一种算法。它的优点是具有平移和旋转不变性，给定曲线与阈值后，抽样结果一定。(Douglas Peucker algorithm is the curve approximated by a series of points, and reduce the number of points of an algorithm. It has the advantages of translation and rotation invariance, given the curve and the threshold, the sampling results must.)

时域自适应滤波中基于先验概率的格型RLS算法(Time-domain adaptive filter based on a priori probability of lattice RLS algorithm)

可以供在SVM门口的初学者早日入门，这些都是最基本的SVM程序，但是也比较专业，希望有需要的人使用(SVM can be at the door for an early entry for beginners, these are the most basic SVM procedure, but more professional, I hope the person has required the use of)

说明：  本程序利用提升方案实现db5/3小波滤波器，并用该小波进行图像的分解(This procedure used to enhance the program to achieve db5/3 wavelet filter, and use the wavelet decomposition for image)

MATLAB编写，可以实现掌纹图像的边缘提取，基于小波模极大值边缘提取。(Image edge detection.)
