My question is very close to this question: How do I gaussian blur an image without using any in-built gaussian functions?
The answer to this question is very good, but it doesn't give an example of actually calculating a real Gaussian filter kernel. The answer gives an arbitrary kernel and shows how to apply the filter using that kernel but not how to calculate a real kernel itself. I am trying to implement a Gaussian blur in C++ or Matlab from scratch, so I need to know how to calculate the kernel from scratch.
I'd appreciate it if someone could calculate a real Gaussian filter kernel using any small example image matrix.
