Mat imageROI = srcImage1(Rect(0, 0, logoImage.cols, logoImage.rows));

Mat mask = imread("C:/Users/离子键/source/repos/Project8/3.jpg", 0);
logoImage.copyTo(imageROI,mask);

namedWindow("<1>利用ROI实现图像叠加示例窗口");
imshow("<1>利用ROI实现图像叠加示例窗口", srcImage1);

return true;
}

bool LinearBlending()
{
   double alphaValue = 0.5;
   double betaValue;
   Mat srcImage2, srcImage3, dstImage;

srcImage2 = imread("C:/Users/离子键/source/repos/Project8/1.jpg");

betaValue = (1.0-alphaValue);
addWeighted(srcImage2, alphaValue, srcImage3, betaValue, 0.0, dstImage);

namedWindow("<2>线性混合示例窗口[原图]", 1);
imshow("<2>线性混合示例窗口[原图]",srcImage2);

namedWindow("<3>线性混合示例窗口[效果图]", 1);

return true;

}

bool ROI_LinearBlending()
{
Mat srcImage4 = imread("C:/Users/离子键/source/repos/Project8/1.jpg");

namedWindow("<4>区域线型图象混合示例窗口");
imshow("<4>区域线型图象混合示例窗口",srcImage4);

return true;
}

运行结果如下：
