code for creating a histogram equalization graph in matlab it convert it first to histogram then perform histogram equlization

说明：  用阈值迭代分割算法对图像进行二值化（matlab）(Iterative segmentation algorithm with the threshold value of the image binarization (matlab))

多个未知数在约束条件下目标函数取最大值得Matlab代码(A number of unknowns in the objective function takes the largest constraints worth Matlab code)

matlab 数值分析中用到的全部代码 很实用(matlab shuzhifenxi)

提出了一种基于 JPEG/JPEG2000相结合的医学图像感兴趣区域压缩方法。该方法对在人为选定 医学图像的感兴趣区域采用无损的 JPEG2000压缩 ,而对其他图像区域则采用高压缩比的 JPEG压缩,较好地解决了医学图像的高压缩比和高质量之间的矛盾。(Based on a combination of JPEG/JPEG2000 region of interest of medical image compression method. The method of artificially selected region of interest of medical images using lossless JPEG2000 compression, and on other image regions using high compression ratio of JPEG compression, a better solution to the medical image and high-quality high-compression ratio between the contradictions.)

一种很好用的光流法，对于图像处理学习的初学者是很不错的参考程序。(A good use of optical flow for image processing is very good for beginners to learn the reference procedure.)

基于邻接矩阵的33节点前推回代配电网潮流程序！(33 nodes based on the adjacency matrix to push back on behalf of the power flow program!)

支持向量机（SVM）主成分分析法进行预处理筛选变量( support vector machine (SVM)，PCA(principal component analysis))
