说明：  logistic混沌映射图，可以得到对logistic混沌映射图和基于logistic对图像加密(Logistic chaotic map)

基于matlab的指纹识别源码 包括预处理、特征点提取和特征点匹配(Fingerprint recognition source code based on MATLAB includes preprocessing, feature extraction and feature matching)

通过PCA+Retinex对图像进行图像增强处理(Image enhancement processing by PCA+Retinex)

说明：  基于IDL语言，使用珠海一号内蒙古地区样例数据、珠海一号贵阳省高光谱数据、Landsat5济南上下幅TM数据（用于拼接验证），实现文件基本操作、遥感图像预处理、高光谱数据处理、生态评价、最大似然法分类、K-Means分类等遥感图像初步处理功能。(Based on IDL language, using Zhuhai No.1 Inner Mongolia area sample data, Zhuhai No.1 Guiyang province hyperspectral data, landsat5 Jinan upper and lower TM data (for splicing verification), the preliminary processing functions of remote sensing image, such as file basic operation, remote sensing image preprocessing, hyperspectral data processing, ecological evaluation, maximum likelihood classification, K-means classification, etc.)

改进分水岭算法，详细注解标在m文件内了，希望对大家有用(Improved watershed algorithm and hope for all of us)

说明：  本代码能实现matlab图中图，可以在figure中实现局部放大图，从而实现整体趋势和局部展示的目的。(This codes can realize the MATLAB graph, iand the codes can realize the local enlargement map in the figure, so as to achieve the overall trend and the purpose of partial display.)

Fritz Keinert写的小波和多小波工具箱(Written by Fritz Keinert wavelet and multiwavelet Toolbox)

说明：  用matlab实现color moments算法，先把rgb图像转换到HSV空间，然后计算每个分量的一二三阶矩，最后组成9维向量进行比较。(Using color moments algorithm matlab realize, first convert rgb images to HSV space, and then calculated for each component of the 123-order moments, the final composition of 9-dimensional vector for comparison.)

对移动目标检测，需要先用鼠标框定感兴趣的目标，然后才能追踪。(Moving target detection, target mouse framed interested need to use before tracking.)

说明：  实现洛伦兹系统分岔图的三种方法，最大值法，庞加莱截面法，getmax法(Three Methods to Realize Lorentz System Bifurcation Diagram)
