（8）图像混合

基础代码展示

#include<iostream>
#include<opencv.hpp>


using namespace std;
using namespace cv;


int main()
{
    Mat src1, src2, dest;
    src1 = imread("C:\Users\32829\Desktop\aa.jpg");
    src2 = imread("C:\Users\32829\Desktop\cc.jpg");
    if (!src1.data) {
        printf("could not load LinuxLogo image...
");
        return -1;
    }
    if (!src2.data) {
        printf("could not load win7logo image...
");
        return -1;
    }
    if (src1.rows == src2.rows && src1.cols == src2.cols) {
        double alpha = 0.5;
        namedWindow("line-blend", CV_WINDOW_AUTOSIZE);
        addWeighted(src1, (1 - alpha), src2, alpha, 0.0, dest);//权重相加
        //add(src1,src2,dst,Mat());//直接将两张图对应的像素相加
        //add(src1,src2,dst,1.0);//直接将两张图对应的像素相乘
        imshow("line-blend", dest);
        waitKey(0);
        return 0;
    }
    else {
        printf("image size is not same...
");
        return -1;
    }

}
