I am trying to unwarp a radial distorted image. I have the parameters cx, cy, k1, k2. These parameters were calculated by someone else and I have no idea what fx and fy are. I thought that if I put fx and fy as 1 (one) these values should work.
this is the line in the code which I use
ippiUndistortRadial_8u_C1R (srcImg, srcStep, destImg, destStep, size, fx, fy, cx, cy, k1, k2, NULL);
when I try to display destImg. I get a black image. Is there something that I am doing wrong??
