opencv5-图像混合

代表一幅图像。代表权重，取值范围为0~1。代表另一幅图像

对图像的每一个像素进行此操作。得到混合后图像

 我的实践：

#include<opencv2\opencv.hpp>
#include<iostream>
#include<math.h>
using namespace cv;
using namespace std;
//线性混合操作
//相关API
int main()
{
	Mat src1 = imread("E:\\vs2015\\opencvstudy\\3.jpg", 1);
	if (!src1.data)
	{
		cout << "could not load image1!" << endl;
		return -1;
	}
	Mat src2 = imread("E:\\vs2015\\opencvstudy\\4.jpg", 1);
	if (!src2.data)
	{
		cout << "could not load image2!" << endl;
		return -1;
	}
	imshow("src1", src1);
	imshow("src2", src2);
	Mat dst,dst1;
	double alpha = 0.5;
	if (src1.rows == src2.rows && src1.cols == src2.cols && src1.type()==src2.type())
	{
		addWeighted(src1, alpha, src2, (1 - alpha), 0, dst, -1);
		//add(src1, src2, dst1,Mat()); 效果不好
		//multiply(src1, src2, dst1, 1.0);
		imshow("addWeightImage", dst);
		imshow("addWeightImage1", dst1);

	}
	else
	{
		cout << "could not blend images.the size of iamges is not same!!!" << endl;
		return -1;
	}
	
	waitKey(0);
	return 0;
 }
