ostu算法（最大类间房差法，类属于阈值分割）的maltab代码，用于计算机图像处理分割及其相关应用。(ostu algorithm (the largest difference room category, type of threshold segmentation is) the maltab code, used in computer image processing and related partition application.)

Jsteg隐写算法[23][24]由D. Upham提出，该算法将秘密信息嵌入在量化后的DCT系数的LSB上，但值为-1、0、+1的DCT系数例外。提取秘密信息时，也只是将隐藏信息的图像中不等于-1、0、+1的量化DCT系数的LSB取出即可(steganography of jsteg)

这个代码是基于论文“Saliency Detection via Graph-Based Manifold Ranking”下的程序源码，作者是Chuan Yang, Lihe Zhang, Huchuan Lu, Ming-Hsuan Yang, and Xiang Ruan 功能1：使用canny算子计算图像的二值边缘图 (The code is for paper "Saliency Detection via Graph-Based Manifold Ranking" by Chuan Yang, Lihe Zhang, Huchuan Lu, Ming-Hsuan Yang, and Xiang Ruan Procedures: 1. compute a binary edge map of the image using the canny method. )

一个求多边形面积的程序 也许会对某些人有用(Area of a polygon for the procedure may be useful to some people)

说明：  两种基于非下采样变换图像去噪方法，效果比contourlet变换要好(Two transform based image denoising nonsubsampled method, the effect is better than contourlet transform)

说明：  图形图像处理经典模型—tv模型的matlab源代码以及所需的图片(Graphic image processing classical model-tv model matlab source code, as well as the picture)

Contrast Stretching in Matlab

亚像素级cvFindCornerSubPix角点检测，可较为精确地对角点进行检测(The subpixel cvFindCornerSubPix corner detection)

一种基于匈牙利算法和相关向量机的点模式匹配算法，可以有效解决点集的刚性和非刚性变换的参数求解问题。(A point set registration method based on Hungarian Algorithm and RVM which can well solve the parameters of rigid and non-rigid transform.)

基于自适应的PCNN(神经耦合网络)融合,对图像的融合起到了很好的作用,是像素级的融合.尤其对于可见光和红外图像有很好的融合效果.(It is based upon the PCNN fusion which has a great effect on image fusion,especially when dealing with infrared picture and visible light picture.)
