说明：  实现峰值信噪比的算法，用于判断图片质量的好坏！十分有用！(Achieve peak signal-to-noise ratio (PSNR) algorithm for judging image quality! Very useful!)

off文件读取绘图函数，能读取顶点坐标和拓扑关系，并以此绘制三维模型图像，使用可以直接调用，需要注意参数的类型，只能读要取off(Off file to read the drawing function, can read the vertex coordinates and topological relations, and in order to draw the three-dimensional model images, the use of direct calls, you need to pay attention to the type of parameters, can only read to take off )

基于matlab的图像分解重构的源码，基于matlab的图像分解重构的源码。。。(The reconstruction of the image decomposition based on matlab source code, the reconstruction of the image decomposition based on the matlab source code..)

通过循环去多个种子点实现基于区域生长的图像分割(Achieve image segmentation based on region growing cycle to go through multiple seed points)

vc编写数字图像处理的程序,其中有图像处理的各种方法的程序(Vc write a digital image processing program, including the various methods of image processing program)

说明：  QR二维码识别中在对图像预处理后最重要的一步就是要进行定位，QR二维码中有三个位置探测图形，通过扫描其特征便可以进行精细定位，提出了一种新的算法用于筛选候选点。(In QR code recognition, the most important step after image preprocessing is to locate. There are three position detection patterns in QR code, which can be precisely located by scanning its features. A new algorithm is proposed to screen candidate points.)

由遥感图像的日数据生成旬数据，一是输出旬数据总和，二是输出旬数据平均值(From the date of remote sensing image data generated late data, the sum of ten days one output data, the second is the average of the output data late)

ostu图像分割阈值算法,对Ostu图像分割最优阈值进行优化处理，极大缩短了搜索图像阈值计算时间，与传统的枚举法Otsu方法相比,在计算时间上具有显著的优点。(ostu threshold image segmentation algorithm for image segmentation Ostu optimal thresholds to optimize the processing, greatly reduces the search image thresholding computation time, with the traditional enumeration method Otsu methods, in the calculation of time has significant advantages.)

图像融合，加权平均值，PCA方法，拉普拉斯方法，源程序(Image fusion, weighted average, PCA method, Laplace method, source)

基于角点特征的图像匹配的几个代码~~较为详细~~~(Corner Feature-based image matching of several more detailed code ~ ~ ~ ~ ~)
