Use Image Functions

This palette groups several functions that analyze the content of an image to obtain information you specify. This palette also contains functions you can use to modify the geometry of the image, calibrate the image so you can make measurements in real-world units, and correct the image.

Histogram

Use this function to count the total number of pixels in each grayscale value and graph the results. You can use the histogram to determine if the overall intensity of your image adequate for your inspection task or if the image contains distinct regions of certain grayscale values.

Line Profile

Use this function to analyze the grayscale distribution along a line of pixels in an image. You can use a line profile to examine boundaries between components, quantify the magnitude of intensity variations, and detect the presence of repetitive patterns.

Measure

Use this function to calculate the position, length, angle, or area of a region of interest in an image.

3D View

Use this function to display the light intensity of an image in a three-dimensional coordinate system, where the spatial coordinates of the image form two dimensions and the light intensity forms the third dimension.

Brightness

Use this function to alter the brightness, contrast, and gamma of an image.

Set Coordinate System

Use this function to build a coordinate system based on the location and orientation of a reference feature.

Image Mask

Use this function to build a mask from an entire image or a selected region. You can use image masks to focus your processing or inspection on particular regions in the image.

Geometry

Use this function to modify the geometrical representation of an image by transforming, rotating, or resampling the image data.

Image Buffer

Use this function to store and retrieve images from buffers.

Get New Image

Use this function to open a new image from a file.

Image Calibration

Use this function to calibrate an image to make measurements in real-world units.

Calibrate from Image

Use this function to apply the calibration information in an image file to the current image.

Image Correction

Use this function to transform a distorted image acquired in a calibrated setup by correcting perspective errors and lens distortion.

Overlay

Use this function to overlay figures, text, and bitmaps onto an image without destroying the image data.

Run LabVIEW VI

Use this function to run a user-specified LabVIEW VI within the Vision Assistant script.
