keypointExtraction

实现了单色图像的JPEG2000编码图像和解码图像！计算其压缩比和误差，观察源图像和重构图像之间的差别！(JPEG2000 images to achieve a monochrome image coding and decoding image! Calculate the compression ratio and error, observation of the source image and the difference between the reconstructed image!)

基于核函数的SAR图像目标识别,利用KPCA对SAR图像进行特征提取(SAR image target recognition based on kernel function，Use KPCA SAR image feature extraction)

这是一个图像处理相关的matlab工具包，包含了很多写好的可以直接调用的m文件，非常实用(These MATLAB functions were created for the book Digital Image Processing Using MATLAB, 2nd edition, by R.C. Gonzalez, R.E. Woods, and S.L. Eddins, Gatesmark Publishing, 2009. The functions supplement and extend the image )

说明：  matlab上面自动实现相机校准标定的一个工具库(Matlab toolbox for multiphase calibration can realize automatic calibration)

使用马尔可夫随机场进行图像分割，包括标记场、特征场建模和参数估计等，程序可运行。(image segmentation Using Markov random field , including label Field, features field modeling and parameter estimation, the program can run.)

这是一个关于图割算法（graphcut）的MATLAB代码实现的。实现了用MATLAB来实现的参数估计，并且可以用于三维重建。(Here is a graph cut algorithm (graphcut) of the MATLAB code implementation. Achieved using MATLAB to implement the parameter estimation, and can be used for three-dimensional reconstruction.)

正则化工具,里面有TV正则化，用超分辨率重建(regulation tool)

自写M函数，做灰度图像的灰度级数及灰度范围的自定义设置。例如：将[0 255]的uint8图像变换成8级灰度的灰度范围为[0 7]图像或者[11.5 25.8]图像。 输出图像为double类，用户可将图像归一化后自行转换为所需类型。(This is a M function written by self, it can be used to rebuild a image with a given number of gray-level and a given gray-scale. Output image is double class.)

广度优先搜索和深度优先搜索在网络拓扑图上的实现。广度优先搜索是从某一节点开始，搜索与其线连接的所有节点，按照广度方向像外扩展，直到不重复遍历所有节点；深度优先搜索是从某一节点开始，沿着其搜索到的第一个节点不断深入下去，当无法再深入的时候，回溯节点，然后再在回溯中的某一节点开始沿另一个方向深度搜索，直到不重复的遍历所有节点。 (Breadth-first search and depth-first search in the network topology is realized. Breadth-first search is started from a node, searching all the nodes connected to its line, in accordance with the breadth direction as extracapsular extension, until no repeat traverse all nodes depth-first search is started from a node along its search to the first nodes deepening it, when it can not go any further, backtracking node, and then back again in the beginning of a node depth search in the other direction until the non-repetition of the traverse all nodes.)

说明：  LSB替换隐写软件，该软件能把ASCII码嵌入到图像中，其载体图像是24位的BMP格式图像(LSB replaces steganography software, which can embed ASCII code into image, and its carrier image is 24 bit BMP format image)
