Issue in imgproc -> Floodfill function
I have a method that uses floodfill function on an image. The issue is that I get different results when running the code on different machines, even with same opencv version. Has anyone else experienced this issue? I can't figure out what is causing this.
floodFill( img, cv::Mat(), cv::Point(img.cols/2,y), cv::Vec3b(255,255,255), 0, cv::Scalar::all(1), cv::Scalar::all(1) , 8 | 255<<8 );
