I have an image ( bit it has a ‘spotty’ appearance). Can you help restore it to a less spotty state

This step was done but i stuck in it how can i make a mask for FFT and make the image without spotty. i think we have to apply notch filter.

%  A=imread('problem8.tif');
%  k=size(A)
% F=fftshift(fft2(double(A)));
% S=log(abs(F));
% imwrite(S/max(S(:)),'mask.tif');
% figure(1),imshow('mask.tif');
