Locates objects in the image similar to the pattern defined in the structuring
element.
A color encoding scheme in hue, saturation, and intensity.
A color encoding scheme using hue, saturation, and luminance information
where each image in the pixel is encoded using 32 bits: 8 bits for hue, 8 bits
for saturation, 8 bits for luminance, and 8 unused bits.
A color encoding scheme in hue, saturation, and value.
Represents the dominant color of a pixel. The hue function is a continuous
function that covers all the possible colors generated using the R, G, and
B primaries. See also RGB.
Hertz. Frequency in units of 1/second.
Input/output. The transfer of data to/from a computer system involving
communications channels, operator interface devices, and/or data
acquisition and control interfaces.
A two-dimensional light intensity function f (x, y) where x and y denote
spatial coordinates and the value f at any point (x, y) is proportional to the
brightness at that point.
A user-defined region of pixels surrounding an image. Functions that
process pixels based on the value of the pixel neighbors require image
borders.
An image that contains thumbnails of images to analyze or process in a
vision application.
A memory location used to store images.
The number of values a pixel can take on, which is the number of colors or
shades that you can see in the image.
A window or control that displays an image.
