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(:));

end
