I am trying to do retial blood vessel extraction and in that process I need to apply a gaussian filter

for |x| ≤ 3σ, |y| ≤ L for a retinal image.

The image will be filtered by g (x, y) in eight directions. Each of the eight filtering responses will be thresholded to generate a vessel map. Finally, the eight vessel maps are fused through a logical OR operation.

Can anyone suggest me how to do it?

Thank you
