Computing the Fourier transform of the Laplacian result in spatial domain is equivalent to multiplying the F(u, v), Fourier transformed function of f(x, y) an input image of size M*N, and H(u, v), the filter used for implementing Laplacian in frequency domain. This dual relationship is expressed as Fourier transform pair notation given by_____________ F(u,v) b) ∇2 f(x,y)↔-F(u,v) c) ∇2 f(x,y)↔-F(u,v) d) ∇2 f(x,y)↔F(u,v)
