Contrast - Multiple ROI
In the Feature Finding and Flaw Detection Drawers
The Contrast - Multiple ROI tool checks the pixels within multiple ROIs and provides the percentage or area
of pixels that are outside and inside a range that is based on user-defined parameters.
The Contrast - Multiple ROI tool evaluates each ROI individually, against a common tolerance, and pro-
vides a detailed list of outputs. The Contrast tool evaluates all of its ROIs as a total group against a common
tolerance and provides combined outputs.
