圖像混合
參數1:輸入圖像Mat-src1;
參數2:輸入圖像Mat-src1的alpha值;
參數3:輸入圖像Mat-src2;
參數4:輸入圖像Mat-src2的alpha值(1-alpha);
參數5:gamma值,默認為0;
參數6:輸出混合圖像
函數功能將兩幅圖像相加,註意兩幅圖像類型必須相同,否則相加會出現錯誤,這個API是opencv自帶的,也可以直接用add(src1,src2,dst,Mat()),來操作,效果沒有addWeighted
源代碼如下:
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
Mat src1, src2, dst;
src1 = imread("C:/Users/Administrator/Desktop/3.jpg");
src2 = imread("C:/Users/Administrator/Desktop/4.jpg");
if (!src1.data)
{
cout << "the image src1 could not load..." << endl;
return -1;
}
if (!src2.data)
{
cout << "the image src2 could not load..." << endl;
return -1;
}
double alpha = 0.5;
if (src1.rows == src2.rows && src1.cols == src2.cols && src1.type() == src2.type())
{
addWeighted(src1, alpha, src2, (1.0 - alpha), 0.0, dst, -1);//圖像相加
//add(src1, src2, dst, Mat());
imshow("src1", src1);
imshow("src2", src2);
imshow("blend image", dst);
imwrite("C:/Users/Administrator/Desktop/blend image.jpg", dst);
}
else {
printf("could not blend images,the size of image is not same\n");
return -1;
}
waitKey(0);
return 0;
}
