Assuming that the origin of F(u, v), Fourier transformed function of f(x, y) an input image, has been correlated by performing the operation f(x, y)(-1)x+y prior to taking the transform of the image. If F and f are of same size M*N, then which of the following is an expression for H(u, v), the filter used for implementing Laplacian in frequency domain?

  1. H(u, v)= -(u^2+ v^2)
  2. H(u, v)= -(u^2– v^2)
  3. H(u, v)= -[(u – M/2)^2+ (v – N/2)^2].
  4. H(u, v)= -[(u – M/2)^2– (v – N/2)^2].
