Video Test Reference Architecture: Digital Video Analysis and Stream to Disk The Example programs demonstrates a simple digital video pixel test with the data being streamed to disk as it is tested. This works well due to the high speed of the PXIe bus. Software: LabVIEW Professional Development System Hardware: High-Speed Digital I/O
Battery Clamp Inspection This example loads a template image that is matched in each new image to locate the new coordinate system. The example repositions measurement areas in the image according to the location of the coordinate system found.
Color Matching Example This example shows how to use IMAQ ColorMatch to check LEDs on the front panel of an instrument. This example compares the color inside each region of interest (ROI) that surrounds an LED to the color spectrum of the expected color. The VI uses another example to learn the color spectrums.
Extract a ROI Example This example shows how to extract one region of an image into a new image. Learn more about common image processing algorithms and see case studies at Analysis in Machine Vision Applications
Fuse Inspection Example This example loads a reference image that defines the coordinate system for the inspection task. The example then loads two templates that define the aspect of a good part.
Fusebox Inspection This example shows how to use color pattern matching to perform production test. The template of a specific fuse identified by its shape and color is located in the assembled product, or the fusebox.
Line Profile This example shows how to use the display tools to draw a line on the window that displays an image and get the pixel values of the image along that line (line profile). You typically use line profiles in inspection and gauging tasks to find the edges of an object or part being inspected.
Customizing the Inspection Interface in Vision Builder AI This example illustrates how to use an image display for the current image, and a smaller image display to show the last failed image. The state diagram for this inspection goes to a state that updates the failed image and timestamp of the failed image when the inspection fails.

Morphological Segmentation Example This example demonstrates a watershed transform as part of a morphological segmentation process. First, a sample image is thesholded, and a distance transform is applied to the sample image. Next, a watershed transform is applied to the image.
Nonlinear Calibration Example This example loads the image of a calibration grid used to calibrate the system, learns the grid, then loads an image of parts acquired using the same setup. The example then corrects the image in two ways. The first method corrects the entire image and then measures the area of the coins.
