2017-06-12 11:23:11 -0600	commented answer	Comparison betweens resize/interpolation algorithms Thank you for your help. I figure out that I wasn't using factor size as a parameter. It is working now.

2017-05-12 14:11:02 -0600	asked a question	Comparison betweens resize/interpolation algorithms 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);`

2017-03-28 13:27:03 -0600	asked a question	How to implement a bilinear/bicubic interpolation algorithm on Opencv using CUDA? Good evening. I just started using Opencv and I would like to use a bilinear/bicubic interpolation algorithm to enhance an image's resolution. I have read some articles about it but I still don't understand how the implementation will be using opencv and C++. Could someone lend me a hand please? The version of Opencv is 3.1.0 and I'm using eclipse mars as IDE.
