Color lookup table. Table for converting the value of a pixel in an image
into a red, green, and blue (RGB) intensity.
Images containing color information, usually encoded in the RGB form.
The technique that locates a color template in a color image based on only
the color information.
The technique that compares the color information in an image or region of
an image to the color information in another image or region of an image.
The technique that locates a color template in a color image based on both
the color information and grayscale pattern in the template.
The mathematical representation for a color. For example, color can be
described in terms of red, green, and blue; hue, saturation, and luminance;
or hue, saturation, and intensity.
Stores information obtained from the FFT of an image. The complex
numbers that compose the FFT plane are encoded in 64-bit floating-point
values: 32bits for the real part and 32bits for the imaginary part.
Defines which of the surrounding pixels of a given pixel constitute its
neighborhood.
Only pixels adjacent in the horizontal and vertical directions are considered
neighbors.
All adjacent pixels are considered neighbors.
(1) A constant multiplication factor applied to the luma and chroma
components of a color pixel in the color decoding process.
(2) The difference between light and dark intensity values in an image.
Computes the convex regions of objects in a binary image.
The smallest convex polygon that can encapsulate a particle.
See linear filter.
2D matrices (or templates) used to represent the filter in the filtering
process. The contents of these kernels are a discrete two-dimensional
representation of the impulse response of the filter that they represent.
