针对彩色图像的局部直方图均衡化，可以较好的增强图像细节(poshe,it can enhancements the detail of the image )

matlab编写的截断半径45时，低通滤波器对与图像的影响，画图比较滤波前后的对比图。(matlab truncation radius of the preparation of 45, the low-pass filter and image of the effect of drawing the contrast to compare before and after filtering Fig.)

卡尔曼滤波在目标跟踪中应用仿真研究 简要讨论了用Kalman滤波方法对单个目标航迹进行预测，并借助于Matlab仿真工具，对实验的效果进行评估。(Kalman filter target tracking simulation study brief discussion of the Kalman filtering method to predict a single target track, and by means of Matlab simulation tools to evaluate the effect of the experimental.)

说明：  特征检测与匹配的目标是识别一个图像中的关键点与另一个图像中的对应 点之间的配对。(The goal of feature detection and matching is to identify the key points in one image and the corresponding points in another image)

通过低通滤波器，实现对图像的平滑处理，使得图像的对比度变低，具有膨胀的效果。(Low-pass filter, to achieve smoothing of the image, so that the image contrast is low, having an expansion effect.)

使用极限学习机ELM算法进行遥感图像分类的源代码，很好的例子(Use extreme learning machine ELM remote sensing image classification algorithm source code, a good example)

pca for color space, Principal component analysis image proccesing for image color

几种图像增强的方法，有双直方图均衡，函数均衡等几种方法(several image enhancement methods, a double histogram equalization, function balance methods)

图片处理 去噪音，去模糊为了实现较好保留图像边缘特征的有效去噪,提出了一种基于边缘检测的Contourlet 变换去噪方法(Picture Deal)

本代码主要是harris角点提取，ncc算法进行粗匹配，然后ransac算法剔除误匹配点(harris ncc ransac)
