- 嵌套opencv的图像像素显示，可直接在vS中打开，或者加入工程-Nested opencv image pixel display, can be directly vS open, or join the project
indexfromPNG.cpp.tar
- 利用libpng库解码读取png图片，获取图片像素的颜色索引值，并将结果保存在opencv的Mat数据容器中。-The color index value for each pixel of a png pixture is given by this code with the help of libpng library. The result is saved in Mat class of opencv.
1Showimagepixcel
- 读入图片，显示到窗口中，通过鼠标点击图片上的相应点，自动读取该点的像素坐标和灰度值。opencv+vs2010-Reads the image displayed in the window, through the corresponding point on the image mouse click, automatically reads the pixel coordinates and gray value at that point. opencv+ vs2010
colorSignature
- 用openCV提取图片的象素值，用聚类进行分割，找出各个聚类的中心点，聚类个数是动态决定的，可重新设置个数最大上限。-OpenCV extract images using pixel value segmentation by clustering to identify the center of each cluster, clustering is a dynamic number of decisions can be re-set the upper limit of the num
roi
- 图像. rect ROI 矩形. 函数 cvSetImageROI 基于给定的矩形设置图像的 ROI（感兴趣区域） . 如果ROI是NULL 并且参数RECT的值不等于整个图像, ROI被分配. 不像 COI, 大多数的 OpenCV 函数支持 ROI 并且处理它就像它是一个分离的图像 (例如, 所有的像素坐标从ROI的左上角或左下角（基于图像的结构）计算。-Image. Rect ROI rectangle function cvSetImageROI given set o
23_UseAtAccessPixel
- 在OpenCV用动态地址计算配合at访问像素-In OpenCV computing with access at a pixel with a dynamic address
提取像素值
- 使用opencv 提取像素点，工具vs2013(Extracting pixel points)
coutour
- Opencv用cvFindContours方法获取获取的轮廓，获取这些轮廓内部的像素点坐标等信息(Opencv uses the cvFindContours method to get the contour and get the information such as pixel coordinates.)
