### Image Enhancement in Frequency Domain

Image Enhancement in Frequency Domain. Image and Its Fourier Spectrum. Basic Steps Multiply pixel f(x,y) of the input image by (-1) x+y . Compute F(u,v), the DFT G(u,v)=F(u,v)H(u,v) g1(x,y)=F -1 {G(u,v)} g(x,y) = g1(x,y)*(-1) x+y. Filtering in Frequency Domain: Basic Steps. Notch Filter.
