Glossary-2
DIB Device-independent bitmap, an image format
used by the library in Windows environment.
dilation A morphological operation that sets each output
pixel to the minimum of the corresponding input
pixel and its 8 neighbors.
dyadic operation An operation that has two input images. It can
have other input parameters as well.
erosion A morphological operation that sets each output
pixel to the maximum of the corresponding
input pixel and its 8 neighbors.
FFT Acronym for the fast Fourier transform. See
Fast Fourier Transform” in Chapter 7.
four-channel model A color model that uses four color channels; for
example, the RGBA color model.
geometric transform
functions
Functions that perform geometric
transformations of images: resizing, rotation,
mirror, shear, and warping functions.
gray scale image An image characterized by a single intensity
channel so that each intensity value corresponds
to a certain shade of gray.
HLS Hue-lightness-saturation. A three-channel color
model that uses hue, lightness, and saturation
channels. The HLS and HSV models differ in
the way of scaling the image luminance. See
HSV.
HSV Hue-saturation-value. A three-channel color
model that uses hue, saturation, and value
channels. HSV is often used as a synonym for
the HSB (hue-saturation-brightness) and HSI
(hue-saturation-intensity) models. See HLS.
hue A color channel in several color models that
measures the “angular” distance (in degrees)
from red to the particular color: 60 corresponds
to yellow, 120 to green, 180 to cyan, 240 to
blue, and 300 to magenta. Hue is undefined for
shades of gray.
