Color encoding scheme in Hue, Saturation, and Intensity.
Color encoding scheme using Hue, Saturation, and Luma information
where each image in the pixel is encoded using 32 bits: 8 bits for hue, 8 bits
for saturation, 8 bits for luma, and 8 unused bits.
Horizontal synchronization signal. The synchronization pulse signal
produced at the beginning of each video scan line that keeps a video
monitor's horizontal scan rate in step with the transmission of each
new line.
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.
The value added to all hue values so that the discontinuity occurs outside
the values of interest during analysis.
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.
Integrated circuit.
Institute of Electrical and Electronics Engineers.
Image acquisition.
Inches.
A set of high-level software functions, such as NI-IMAQ, that control
specific plug-in computer boards. Instrument drivers are available in
several forms, ranging from a function callable from a programming
language to a virtual instrument (VI) in LabVIEW.
