When should I choose a Dip filter over an F-K filter?

Both processes remove linear noise but there are some circumstances in which one works better than the other:

  • F-K can filter on certain frequencies. This helps when noise occurs within a specific frequency range.
  • F-K tends to work better when spatial resolution is poor.
  • Dip filter works better if there is aliasing in the F-K domain.
