OpenCV 程式碼讀取影象並進行比較

#include <opencv2 / opencv.hpp> #include

使用名稱空間 cv; 使用名稱空間 std;

int main（int argc，char ** argv）{Mat image; image = imread（“C：\ Users \ Development \ Documents \ Visual Studio 2013 \ Projects \ ImageIn.bmp”，CV_LOAD_IMAGE_GRAYSCALE）; //讀取檔案

if (!image.data)                              // Check for invalid input
{
    cout << "Could not open or find the image" << std::endl;
    return -1;
}

Mat witout = imread("C:\\Users\\Development\\Documents\\Visual Studio 2013\\Projects\\ImageWitOut.bmp", CV_LOAD_IMAGE_GRAYSCALE);;
Mat cvout = Mat(image.size(), image.type(), Scalar(255));

imshow("cvout", cvout);

imshow("Difference", diff);                   // Show our image inside it.
