IMAQ Vision Function Types
Function Type Description
Image
Management
Functions that create space in memory for images and perform basic image
manipulation.
Memory
Management
A function that returns memory you no longer need to the operating system.
Error
Management
Functions that set the current error, return the name of the function in which the
last error occurred, return the error code of the last error, and clear any pending
errors.
Acquisition Functions that acquire images through an IMAQ hardware device.
Display Functions that cover all aspects of image visualization and image window
management.
Overlay Functions that create and manipulate overlays.
Regions of
Interest
Functions that create and manipulate regions of interest.
File I/O Functions that read and write images to and from files.
Calibration Functions that learn calibration information and correct distorted images.
Image Analysis
Functions that compute the centroid of an image, profile of a line of pixels,
and the mean line profile. This type also includes functions that calculate the
pixel distribution and statistical parameters of an image.
Grayscale
Processing
Functions for grayscale image processing and analysis.
Binary
Processing
Functions for binary image processing and analysis.
Color
Processing
Functions for color image processing and analysis.
Pattern
Matching
Functions that learn patterns and search for patterns in images.
Caliper Functions designed for gauging, measurement, and inspection applications.
Operators Functions that perform arithmetic, logic, and comparison operations with
two images or with an image and a constant value.
Analytic
Geometry
Functions that perform basic geometric calculations on an image.
