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.

Region of interest

From Wikipedia, the free encyclopedia

A Region of Interest, often abbreviated ROI, is a selected subset of samples within a dataset identified for a particular purpose.
For example:

on a waveform (1D dataset), a time or frequency interval
on an image (2D dataset), the boundaries of an object
in a volume (3D dataset), the contours or surfaces outlining an object
in a time-volume (4D dataset), the outline of an object at or during a particular time interval
The concept of an ROI is commonly used in medical imaging. For example, the boundaries of a tumor may be defined on an image or in a volume, for the purpose of measuring its size. The endocardial border may be defined on an image, perhaps during different phases of the cardiac cycle, say end-systole and end-diastole, for the purpose of assessing cardiac function.
