DCT

说明：  用数学形态学滤波进行图像处理或者信号降噪，（包括膨胀和腐蚀）(Image processing or signal noise reduction using mathematical morphological filtering (including expansion and corrosion))

说明：  利用K均值聚类对图像lena进行分割，图片可根据需求进行更换。(Image Lena is segmented by k-means clustering, and the image can be replaced according to the demand.)

说明：  图像梯度计算 遥感图像处理必备 非常实用 欢迎下载(Remote sensing image processing image gradient calculation is very useful are welcome to download necessary)

说明：  我是一个图象处理的初学者,用MATLAB语言编写了一些内部的函数,实现了图象处理的功能,比如entropy,laplician,otsu,top-hat等(image processing is a beginners MATLAB language some internal functions, achieving image processing functions, such as entropy, laplician, Otsu, top-hat, etc.)

这是我花了很多时间收集的有关sift-pca资料哦，里面也包括了sift-pca的MATLAB代码(This is what I spent a lot of time to collect information about the sift-pca Oh, which also includes a sift-pca MATLAB code)

能计算图像的灰度直方图，及其对应的灰度均值(calculate means ，variance，bins)

ant蚁群算法,求解局部或者全局优化问题,(Ant colony algorithm to solve local or global optimization problems,)

说明：  利用matlab从某张图片中提取或删除某种颜色的背景。(extract/delete certain color from a picture)

图片的旋转、截图、灰度、翻转、滤波、去噪等基本处理(Image rotation, screenshots, gray, flip, filtering, noise and other basic processing)

基于颜色特征的图像检索系统，，做 了GUI节目，直观(Color-based Image Retrieval System, made a GUI program, intuitive)
