Well, the MSCN image output is not shared in the paper, but I'll share the link soon. As far as the plot is concerned,

Agreed, specially the otsu threshold and gray conversion method. Color doesn't help here, most probably. The best way wo

Ohkay, is there any possibility of a slight difference in Gaussian Blur of C++ and Python?

2018-06-02 02:40:24 -0500 marked best answer Conversion of C API to C++ API problem

I have the following lines of code in C API :

  IplImage *imdist_scaled = cvCreateImage(cvSize(orig_bw->width/pow((double)2,itr_scale-1), orig_bw->height/pow((double)2,itr_scale-1)), IPL_DEPTH_64F, 1);
    cvResize(orig_bw, imdist_scaled,CV_INTER_CUBIC);

And I've converted it into C++ API as :

Mat imdist_scaled(Size(orig_bw.cols/cv::pow((double)2, itr_scale-1), orig_bw.rows/pow((double)2, itr_scale-1)), CV_64F, 1);

  resize(orig_bw, imdist_scaled, imdist_scaled.size(), 0, 0, INTER_CUBIC); // INTER_CUBIC
  imdist_scaled.convertTo(imdist_scaled, CV_64FC1); // if not done, then it shows error in later steps
  // depth == 5 || 6 check error in pow function

In first case, when I try to show the image to the screen (imdist_scaled) - it shows me resized image. But in the second case, when I do the same, it shows a blank white image.

When I check the output without using convertTo command, then it works but in the later steps it says depth error, and thus I've converted it to 64F depth, which unfortunately leads it to be a blank white image.

Also note that I've verified orig_bw.cols, orig_bw.rows etc. have correct outputs.

Here orig_bw is a sample image I'm taking.

Why would that be?

Thanks @berak. Have one more doubt, in functions, there is IplImage* object being passed. I'm passing Mat object then.
