Unformatted text preview: then apply inverse FFT to recover the original grayscale image. The transformed values should be complex numbers, and their magnitude must be computed to decide whether they should be cut off, that is, they should be enforced to be zero. The values whose magnitude is large, should be retained. (3) Instead of FFT, apply a wavelet transformation available in MATLAB, and repeat the same with (2)....
