--- Start of Idrisi List message Hi, I want to perfom a Fourier Analysis on Landsat MSS and TM data so I can then perform a supervised classification to determine land cover, which Filter type would be best in FILTERFQ - Homomorphic or Butterworth or another? Could anybody please explain how to determine the value to use for the 'cut off frequency' option.
