opencv学习之路(4)：图像的叠加，add、addweighted、‘+’

1、图像的叠加

#include <iostream>
#include "opencv2/opencv.hpp"
using namespace std;

int main()
{
    cv::Mat matImage1 = cv::imread("E:/QtMaterial/images/boldt.jpg");
    cv::Mat matImage2 = cv::imread("E:/QtMaterial/images/rain.jpg");
    cv::Mat result;
    float flag,k1,k2,k3;
    while(flag != 9)
    {
        cout<<"c[i]=k1*a[i]+k2*b[i]+k3"<<endl;
        cout<<"flag k1 k2 k3"<<endl;
        cin>>flag>>k1>>k2>>k3;
//         cv::addWeighted(matImage1,k1,matImage2,k2,k3,result);
        result = k1*matImage1+k2*matImage2+k3;
        cv::imshow("Process",result);
        cv::waitKey();
        cv::destroyWindow("Process");
    }
    return 0;
}

代码2，vector<cv::Mat>planes;split,merge

#include <iostream>
#include "opencv2/opencv.hpp"
using namespace std;

int main()
{
    cv::Mat matImage1 = cv::imread("E:/QtMaterial/images/boldt.jpg");
    cv::Mat matImage2 = cv::imread("E:/QtMaterial/images/rain.jpg",0);
    std::vector<cv::Mat>planes;
    cv::Mat result;
    float flag=0,k1,k2,k3;
    uchar k;
    while(flag != 9)
    {
        cout<<"flag"<<endl;
        cin>>flag;
        if(flag==1){
            cout<<"c[i]=k1*a[i]+k2*b[i]+k3"<<endl;
            cout<<"k1 k2 k3"<<endl;
            cin>>k1>>k2>>k3;
    //         cv::addWeighted(matImage1,k1,matImage2,k2,k3,result);
            result = k1*matImage1+k2*matImage2+k3;
            cv::imshow("Process1",result);
            cv::waitKey();
            cv::destroyWindow("Process1");
        }

        if(flag ==2)
        {
            cout<<"k"<<endl;
            cin>>k;
            cv::split(matImage1,planes);
            planes[k-'0']+=matImage2;
            cv::merge(planes,result);
            cv::imshow("Process2",result);
            cv::waitKey();
            cv::destroyWindow("Process2");
        }
    }
    return 0;
}
