An enhanced image can be obtained as: g(x,y)=f(x,y)- 2 f(x,y), where Laplacian is being subtracted from f(x, y) the input image of size M*Non which an operation f(x, y)(-1)x+yis applied.Unlike enhancing in spatial domain with one single mask, it is possible to perform the same in frequency domain using one filter. Which of the following is/are the required filter(s)?

tH(u, v)= -[(u M/2)2+ (v N/2)2].

tH(u, v)= [1 + (u M/2)2+ (v N/2)2].

An enhanced image can be obtained as: g(x,y)=f(x,y)- 2 f(x,y), where Laplacian is being subtracted from f(x, y) the input image. What does this conclude?

tThat the center spike would be negative

tThat the immediate neighbors of center spike would be positive.

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_____________

t 2 f(x,y) [(u+M/2)2 (v+N/2)2]F(u,v)

t 2 f(x,y) [(u M/2)2+ (v N/2)2]F(u,v)

t 2 f(x,y) -[(u+M/2)2 (v+N/2)2]F(u,v)

t 2 f(x,y) -[(u M/2)2+ (v N/2)2]F(u,v)

t 2 f(x,y) [(u+M/2)2 (v+N/2)2]F(u,v)
