Hello, I'm trying to evaluate nearest, bilinear and bicubic interpolation algorithms from the resize function but all my images are exactly the same.
Can anyone help me?
Mat img;
Mat img2;
img = imread("face2.png", IMREAD_UNCHANGED);
Size size(720,1080);
vector<int> com_param;
com_param.push_back(CV_IMWRITE_JPEG_QUALITY);
com_param.push_back(9);
cv::resize(img, img2, size, cv::INTER_NEAREST);
imwrite("nearest.jpg",img2,com_param);
cv::resize(img, img2, size, cv::INTER_NEAREST);
imwrite("bilinear.jpg",img2,com_param);
cv::resize(img, img2, size, cv::INTER_NEAREST);
imwrite("cubic.jpg",img2,com_param);
