MFC下使用OPENCV2.31配VS2005,实现图像交并差等操作例子-MFC use OPENCV2.31 with VS2005, the realization of image intersection operation example

OPENCV 摄像机标定程序 可以选取标定范围 保存交点坐标 并排序 程序可用 -OPENCV camera calibration procedure calibration range can be selected and saved intersection coordinates sort program available

vs2013+opencv2.4，用hough直线变换提取3条直线，并求出3条直线交点，得到一个三角形ROI区域-vs2013+opencv2.4, with a straight line hough transform to extract three straight, and find the intersection of three straight, to give a triangular region ROI

计算任意多边形的相交面积和相并面积，用于衡量多边形的重合度(calculate the intersection area and union area of arbitrary polygon)
