Spatial Domain Contrast
The spatial domain is the normal image space, in which a change in position in I directly projects to a change in position in S.
Distances in I (in pixels) correspond to real distances (e.g. in meters) in S.
This concept is used most often when discussing the frequency with which image values change, that is, over how many pixels does a cycle of periodically repeating intensity variations occur. One would refer to the number of pixels over which a pattern repeats (its periodicity) in the spatial domain.
