What is the difference between spatial domain and time domain?
In general, the expressions "time domain" and "spatial domain" refer to the domain of the original or given signal, which can 1D or 2D (or of higher dimensions). The expression "spatial domain" can be used to more specifically refer to the domain of a given image (which is a subset of the 2D).
Why is frequency domain better than spatial domain?
Difference between spatial domain and frequency domain
In spatial domain, we deal with images as it is. The value of the pixels of the image change with respect to scene. Whereas in frequency domain, we deal with the rate at which the pixel values are changing in spatial domain.
What is spatial domain?
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.
What is meant by spatial frequency?
The spatial frequency is defined as line pairs per angular extent of the target, and the phase specifies the relative location of the target image to the detector array raster. From: Encyclopedia of Modern Optics, 2005.
