If the Laplacian in frequency domain is: where is the Fourier transform operator and F(u, v) is Fourier transformed function of f(x, y), then what is -(u^2+ v^2) is considered as?
(a) Laplacian operation
(b) Filtering operation
(c) Shift operation
(d) None of the mentioned
The question was asked in semester exam.
