Adaptive Template
In the Flaw Detection Drawer
The Adaptive Template tool performs a gradient match similar to the Greyscale Template tool. However,
unlike the Greyscale Template tool, no standoff distance is required since this tool automatically ignores
edges while still extracting defects in and around them. This type of search allows the tool to account for
minor errors in locating, and also deals with image lighting variations automatically. See “How the Adaptive
Template tool Works” on page 3-146.
Setting up the Adaptive Template tool
1. Acquire an image of a good part
2. Click the Find Shape List property and define the region of the image to search, if desired.
3. Set the Filter Width property for the maximum pixel distance to search (approximately the size of the
defects to find).
4. Click the Train button.
