Question: 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)?
Options
A : H(u, v)= -[1 + u2+ v2].
B : H(u, v)= -[(u – M/2)2+ (v– N/2)2].
C : H(u, v)= [1 + (u – M/2)2+ (v – N/2)2].
D : All of the mentioned
