（8）图像混合

基础代码展示

 1 #include<iostream>
 2 #include<opencv.hpp>
 3 
 4 
 5 using namespace std;
 6 using namespace cv;
 7 
 8 
 9 int main()
10 {
11     Mat src1, src2, dest;
12     src1 = imread("C:\Users\32829\Desktop\aa.jpg");
13     src2 = imread("C:\Users\32829\Desktop\cc.jpg");
14     if (!src1.data) {
15         printf("could not load LinuxLogo image...
");
16         return -1;
17     }
18     if (!src2.data) {
19         printf("could not load win7logo image...
");
20         return -1;
21     }
22     if (src1.rows == src2.rows && src1.cols == src2.cols) {
23         double alpha = 0.5;
24         namedWindow("line-blend", CV_WINDOW_AUTOSIZE);
25         addWeighted(src1, (1 - alpha), src2, alpha, 0.0, dest);//权重相加
26         //add(src1,src2,dst,Mat());//直接将两张图对应的像素相加
27         //add(src1,src2,dst,1.0);//直接将两张图对应的像素相乘
28         imshow("line-blend", dest);
29         waitKey(0);
30         return 0;
31     }
32     else {
33         printf("image size is not same...
");
34         return -1;
35     }
