Hello, I am interested in your code for Single-Image-Example-Based-Super-Resolution. I have a Question.

After I do build the code by using the Example, I have no error message. But after I run the program I have some error message on the console,

OpenCV Error: Assertion failed (dims <= 2 && data && (unsigned)i0 < (unsigned)size.p[0] && (unsigned)(i1*DataType<_Tp>::channels) < (unsigned)(size.p[1]*channels()) && ((((sizeof(size_t)<<28)|0x8442211) >> ((DataType<_Tp>::depth) & ((1 << 3) - 1))*4) & 15) == elemSize1()) in cv::Mat::at, file c:\opencv\build\include\opencv2\core\mat.hpp, line 538

So, I tried debugging in the code. While debugging, in void gs::makeFreqResp(int filterSize, float p, float q, float s, cv::Mat& H, cv::Mat& G, cv::Mat& h, cv::Mat& g) I had some error in /create the low pass magnitude response/ part. in the for loop, in the else if (kTrans[i] == 1.0), after taking d = (1.0 + cos(wScaled[i]))*sqrt(2.0 - cos(wScaled[i])) / 2, H.at(0, i) = d had some thing wrong. I have no idead why H.at(0, i) = d has some thing wrong. Can you help me for the problem? Thank you for your attention

1. when loading the image, can you verify that the image matrix is not empty?
2. What build configs are you using? I find openCV works when using release configs but not debug configs.
