If i have for example this matrix X=[1 2 3;4 5 6;7 8 9]; and it's DFT transform matrix will be like that >> fft2(X)=[45.0000 + 0.0000i -4.5000 + 2.5981i -4.5000 - 2.5981i;-13.5000 + 7.7942i 0.0000 + 0.0000i 0.0000 + 0.0000i;-13.5000 - 7.7942i 0.0000 + 0.0000i 0.0000 + 0.0000i]. How can i use any threshold methods to have a matrix values between 0 and 255?
