I am going through a research paper and trying to implement it. In the paper it is saying :

That they use the isotrope Gaussian bandwidth Filter, giving a formula and then using the formula they get the frequential map.

My question being, how to apply a particular formula to the matrix image (Section 3.2), and what is the frequential map, as in what format it is?

Link for the paper : Frequential and color analysis for hair mask segmentation

PS : Its difficult for me to write the equation over here, so please bear with me.

I understand that filter is defined in frequency domain: fourier transform of image, multiply by filter and inverse fourier transform and it gives you frequential_mask(i, j)
