  • Dear Megah,
    Use this function to generate 2D gaussian filter with varying kernel size and variance
    %This program generates the 2D gaussian filter.
    %To generate the filter,code should be written as f=gaussian_filter(size_of_kernel,sigma);
    %This code was developed by Vivek Singh Bhadouria, NIT-Agartala, India on 4

    function f=gaussian_filter(n,s)
    x = -1/2:1/(n-1):1/2;
    [Y,X] = meshgrid(x,x);
    f = exp( -(X.^2+Y.^2)/(2*s^2) );
    f = f / sum(f(:));
