The analysis of image content--the conversion of pictures into descriptions.
The synthesis of artificial images--the creation of pictures from descriptions.
The enhancement or other manipulation of an image--the result of which is
usually another image.
A digitally sampled picture.
The ``reality''from which an image was taken.
The amount of detail that can be discerned in an image.
The usual measurement is in separable line pairs per millimeter.
Magnetic Resonance Imaging.
Computed Axial Tomography
Single-Photon Emission Computed Tomography
Positron Emission Tomography
The Fourier transform of an imaging system
Modulation Transfer Function
The magnitude part of a Transfer Function
Phase Transfer Function
The phase part of the Transfer Function
A an image (or function of an image) as measured at multiple scales.
Second spatial derivative.
Nuclear Medical Imaging
An emission modality in which a radioactive pharmaceutical is
introduced into the patient.
Imaging occurs by measuring the low-level radiation given off by
Examples of Nuclear Medical Imaging include
A strictly black and white image (0s and 1s).
One bit of information per pixel.
An image consisting of scalar values
representing intensity. These are usually stored as
one byte per pixel (256 levels) or
two bytes per pixel (65,536 levels).
An image whose values represent distance
from the imaging device.
A single "picture element"--the smallest piece of an image.
The process of recording the value of some function
only at discrete points in the domain.
