That's why I asked how to make same effect as Photoshop with OpenCV. It seems you don't know how to do. 2016-09-29 09:12:04 -0500 asked a question Clone Gaussian Filter of Photoshop I tried Gaussian Blur of OpenCV. But it shows different result from Photoshop. For example, I was asked to input radius in Photoshop. So I typed 25. And by using OpenCV, I coded as follows. cv::Mat cvMat = cv::imread("1.jpg"); // this image is a grayscale image. cv::Mat gb; cv::GaussianBlur(cvMat , gb, cv::Size(25*2+1, 25*2+1), 25);  But I got different result. So I tried 50, instead of 25 and after that, I saw similar result, but still different. What should I do to get the same result as Photoshop Gaussian Filter? Thank you.
