Create Region of Interest Concepts

The Create Region of Interest step creates a region of interest (ROI) for an inspection image. This step allows you to create point, line, rectangle, rotated rectangle, annulus, and oval ROIs.

Create an ROI by drawing a region on the image, or by specifying coordinate values that define the region. You may also use the measurement results from previous steps or the value of a user-defined variable to define the ROI. For example, you can use measurements from a previous step to position the ROI at the center of found objects.

The ROI created by this step can be used in future steps. This allows you to apply several algorithms to the exact same ROI.
