OpenCV 小圖重疊至大圖指定位置

Android OpenCV Java:

Codes:

 smallImg.copyTo( bigImg.submat( y, smallImg.rows(), x, smallImg.cols() ) );

C++:

  image是原圖，logo和mask是小幅圖像，其中182,63,215,235，分別是覆蓋位置左上角的點和覆蓋的width和height

cv::Mat image = cv::imread("D:/imagewarping/testresult/hansome.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();
