Re: What exactly does the Fourier Transform do?

Hi,
1) Look for a nice book
2) keep in mind that the fft command is shifted compared with other
programs/books (help fftshift to solve it)
3) which frequencies would you like to remove/select from your image? (if
you know the answer on this question you have your answer on your question)
Good lcuk,
Redmer
