Owning Palette: Image ProcessingInstalled With: NI Vision Development Module

Use the Processing VIs to process grayscale and binary images. Use these VIs to transform images using predefined or custom lookup tables, change the contrast information in an image, invert the values in an image, and segment the image.

Palette Object Description
IMAQ UserLookup

Performs a user-specified lookup-table transformation by remapping the pixel values in an image.

IMAQ MathLookup

Converts the pixel values of an image by replacing them with values from a defined lookup table. This VI modifies the dynamic range of either part of an image or the complete image, depending on the type of curve chosen.

IMAQ Equalize

Produces a histogram equalization of an image. This VI redistributes the pixel values of an image to linearize the accumulated histogram. The precision of the VI is dependent on the histogram precision, which in turn is dependent on the number of classes used in the histogram.

IMAQ BCGLookup

Applies a brightness, contrast, and gamma correction to an image. The correction is performed by computing and applying a lookup table. Brightness, Contrast, and Gamma control the changes made to the transfer function represented by the lookup table.

IMAQ Threshold

Applies a threshold to an image.

IMAQ MultiThreshold

Performs thresholds of multiple intensity ranges to an image.

IMAQ Label

Labels the particles in a binary image.

IMAQ Watershed Transform

Computes the watershed transform on an image.

IMAQ Inverse

Inverts the pixel intensities of an image to compute the negative of an image.

IMAQ AutoMThreshold

Computes the optimal values to threshold an image into a given number of classes.

IMAQ Local Threshold

Thresholds an image into a binary image based on the specified local adaptive thresholding method.

IMAQ MagicWand

Creates an image mask by extracting a region surrounding a reference pixel, called the origin, and using a tolerance of intensity variations based on this reference pixel.
