opencv图像融合c++代码实例及运行结果

c++代码#include<opencv2/opencv.hpp>
using namespace cv;
using namespace std;

int trackBarValueCurrent = 0;//轨迹条当前值
int trackBarValueMax = 100;//轨迹条最大值
Mat img1, img2,img;
char *windowName = "图像融合";//窗口名称
char *trackBarName = "进度条";//进度条名称

void trackBarFun(int ,void*)
{
float rate = (float)trackBarValueCurrent / trackBarValueMax;
addWeighted(img1, rate, img2, 1 - rate, 0, img);
imshow(windowName, img);
}

int main(int argc, char *argv[])
{
img1 = imread("C:\\Users\\Administrator\\Desktop\\1csdn\\8.png");
img2 = imread("C:\\Users\\Administrator\\Desktop\\1csdn\\9.png");

if (img1.empty() || img2.empty())
{
cout << "图片读取错误" << endl;
exit(1);
}

resize(img1, img1, Size(img2.cols, img2.rows));//将img1的图片大小变为与img2一样
namedWindow(windowName);
createTrackbar(trackBarName, windowName, &trackBarValueCurrent, trackBarValueMax, trackBarFun);
trackBarFun(0,0);
waitKey();

return 0;
}运行结果
