IMAQ Vision for Visual Basic User Manual
The process of improving the quality of an image that you acquire from
a sensor in terms of signal-to-noise ratio, image contrast, edge definition,
and so on.
A file containing pixel data and additional information about the image.
Defines how an image is stored in a file. Usually composed of a header
followed by the pixel data.
A binary image that isolates parts of a source image for further processing.
A pixel in the source image is processed if its corresponding mask pixel has
a non-zero value. A source pixel whose corresponding mask pixel has a
value of 0 is left unchanged.
The gradation of colors used to display an image on screen, usually defined
by a CLUT.
Encompasses various processes and analysis functions that you can apply
to an image.
The original input image.
Any process of acquiring and displaying images and analyzing image data.
Image Acquisition.
Finds the inner boundary of objects.
The process by which parts are tested for simple defects such as missing
parts or cracks on part surfaces.
Analyzes groups of pixels within an image and returns information about
the size, shape, position, and pixel connectivity. Typical applications
include quality of parts, analyzing defects, locating objects, and sorting
objects.
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 VI in LabVIEW.
The sum of the Red, Green, and Blue primary colors divided by three,
(Red + Green + Blue)/3.
