超像素线性分割聚类代码，可以运行，效果比较好，欢迎下载参考(SLIC code)

在matlab中应用牛顿切线法和割线法求解一元多次方程,很好的(In the application of matlab Newton tangent method and secant method solving one yuan equation for many times, very good)

图像颜色聚类分割，实现了图形分割，基于RGB特征并显示出来。(Color image segmentation clustering, to achieve the graphics division, based on the characteristics of RGB and displayed.)

实现热键截图的功能，把截到的图片保存到制定的文件夹中，然后把图片输出到报表中，形成报表！(Achieve hotkey screenshot function, the cut-off to save the picture to develop a folder, and then the picture output in the report, the formation of statements!)

Hu的七个不变矩在图像处理，尤其是特征提取方面是很重要的一个概念。本代码实现了图像的7个不变矩的计算和输出。( Hu s 7 moment invariants is significant in image processing,especially in feature seletcion. This code calculate them.)

pca特征提取子程序，毕设用的，算法优化非常好，几乎没有循环，相当节省时间，堪称经典，运行绝对正确！！(pca feature extraction subroutine, used to complete set up, very good algorithm, almost no circulation, saving considerable time, classic, run absolutely right! !)

在matlab中的分形图像放大程序；对初学者很有用哦！(In the matlab source code to raise the image resolution is indeed very useful!)

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)

实现对图像的任意形状的裁剪。注意：图像裁剪后带有背景色(Realization of arbitrary shape image cropping. Note: the image is cropped with a background color)

说明：  据的规范化程序,消除数据的量纲对处理结果的影响,数据点之间距离的计算程序(According to the standardized program, the influence of the dimension of the data on the processing results is eliminated, and the calculation program of the distance between the data points is obtained.)
