quantizer
A device with a limited number of possible output values (sometimes able to be selected) that can translate an incoming...
binary thresholding
An imaging technique that labels all gray pixels as either black or white before processing begins.
gray scales
Transparencies that represent progressive steps in the amount of transmitted radiation for administering predetermined...
pseudocolor
In image processing, generating a color image from monochrome data by assigning a color to each of the gray levels.
hue
The perceptual term for that aspect of color described by words such as red, yellow or blue. Achromatic colors, such as...
feature extraction
In image processing and machine vision, the process in which an initial measurement pattern or some subsequence of...
posterization
In image processing, the effect caused by large jumps between gray levels, rather than a gradual change.
halftones
The gray-colored tones halfway between shadows and highlights in a reproduced image.
luma
The luminance portion of a composite video signal, i.e., the portion of the signal that corresponds to the brightness of the...
median filtering
In image processing, a method of local smoothing by replacing each pixel with the median gray level of neighboring pixels.
run end coding
A digital imaging method whereby the first gray level in the ordered sequence and the position of the first lengths of all...
fluence
Fluence is a term used in various scientific and technical disciplines to describe the amount of something per unit area....
enhanced graphic adaptor
An image processing device that displays pseudocolor images by assigning colors to the gray scales according to look-up...
gray body
A temperature radiator whose spectral emissivity at all wavelengths is in constant ratio (less than unity) to that of a...
gray-scale modification
Image enhancement operations that involve altering gray-scale values. For instance, brightness sliding involves adding or...
pixel
A pixel, short for "picture element," is the smallest controllable element of a digital image or display. It is a...
infrared camera
An infrared camera, also known as a thermal imaging camera or IR camera, is a device that captures and visualizes the...
gray-scale image
An image consisting of an array of pixels that can have more than two values (black and white). Typically, up to 16 levels...
gray scale
In image processing, the range of available gray levels. In an 8-bit system, the gray scale contains values from 0 to 255.
image contrast
Also referred to as image visibility, the contrast of an image is the variation in the intensity of an image formed by an...
brightness resolution
The degree to which a pixel in a digital image represents the analog brightness of the corresponding point in the original...
nonselective radiator
Also known as a gray body; a nonselective radiator is a thermal radiator that has a constant spectral emissivity with...
dithering
In image processing, modifying the dot that forms the image in order to simulate a series of gray tones.
morphological processing
A set of algorithms used to study the structural and spatial characteristics of objects in a digitized image for...
nonspectral color
A color whose hue is not produced by a single wavelength in the visible spectrum, but is instead produced by mixing the...
gray filter
 edge detection
In image processing, the location of edges by employing templates that respond to the first or second derivative of...
gray
1. A measure of absorbed dose, equal to the energy imparted by ionizing radiation to a mass of matter corresponding to 1 J...
gray levels
In image processing, machine vision and television, discrete brightness values quantized for a group of pixels. They can...
infrared mapping
The process of mapping the infrared emittance of an area through the use of an infrared detector and related scanning...
tonality
The distribution of gray-scale values in an image.
neutral density coating
A coating applied to a neutral density glass that is designed to reduce the amount of light evenly across the transmitted...
