Low Pass Frequency Domain Filters:
The basic formula for any kind of filtering is based on the convolution integral.
i.e. f(x,y)*h(x,y) = FT =F(u,v) x H(u,v)
f(x,y) - original image
h(x,y) - Filtering mask
F(u,v) – Fourier transform of the original image.
H(u,v) – Fourier transform of the filtering mask …
