opencv 片覆盖,opencv选取像局部区域

    image是原图，logo和mask是小幅图像，其中182,63,215,235，分别是覆盖位置左上角的点和覆盖的width和height

cv::Mat image = cv::imread("D:/imagewarping/testresult/zxdss.jpg");cv::Mat logo = cv::imread("D:/imagewarping/testresult/trans.jpg");cv::Mat mask = cv::imread("D:/imagewarping/testresult/trans.jpg", 0);cv::Mat imageROI;imageROI = image(cv::Rect(182, 63, 215, 235));logo.copyTo(imageROI, mask);cv::namedWindow("result");cv::imshow("result", image);imwrite("D:/imagewarping/testresult/plantsrc.jpg", image);cv::waitKey();
