I know that for a given signal, the sampling frequency Fs must be twice or more than maximum frequency of the signal Fm. It is easy to understand the concept for a 1D signal. But I don't know how to calculate sampling frequency or Nyquist rate for a 2D image.(adsbygoogle = window.adsbygoogle || []).push({});

Also what is effect of over-sampling and under-sampling in case of image (dimensions width⋅height=204⋅226)?
