Smoothing Noise

The idea with noise smoothing is to reduce various spurious effects of a local nature in the image, caused perhaps by

• noise in the image acquisition system,
  
• arising as a result of transmission of the image, for example from a space probe utilising a low-power transmitter.

The smoothing can be done either by considering the real space image, or its Fourier transform.
