Explicit fusion of two images of OPENCV learning notes

An explicit fusion of images

That is, by the following formula

Two images are superimposed on each other, and alpha controls the weight of the image in the fused image.

The following two images are implemented using the addweighted () function.

Fig. 1 Fig. 2

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace std;
using namespace CV;
int main ()
{
	Mat img1,img2,out;
	Img1=imread ("1.jpg", 0);
	Img2=imread ("2.jpg", 0);

	if (!img1.data)
		cout<< "Error loading IMG1" <<endl;
	if (!img2.data)
		cout<< "Error loading Img2" <<endl;

	Double alpha=0.5;
	Double beta,input;

	cin>>input;

	if (input>=0.0 && input<=1.0)
		alpha=input;
	Beta= (1.0-alpha);
	Addweighted (img1,alpha,img2,beta,0.0,out);

	Namedwindow ("Out", 1);
	Imshow ("Out", out);

	Waitkey (0);
	return 0;
}

Effect:
Post-Fusion image

The parameters of the function are as follows:
