Q: The Reposition Region of Interest and Reference Coordinate System controls are dimmed. How can I make these options available?
Insert a Set Coordinate System step before this step to make the Reposition Region of Interest and Reference Coordinate System controls available.
Q: What settings does Auto Setup use?
Auto Setup analyzes the pixel information along the region of interest and estimates the parameters that locate the maximum number of strong, distinct edges. The parameter values estimated by Auto Setup appear in the dimmed setting controls.
Q: Why are the edge points different colors?
The blue edge points represent edges whose pixels go from dark to light intensity values. The red edge points represent edges whose pixels go from light to dark intensity values.
Q: What should I do if the step does not find the edges but the Edge Strength Profile shows definite peaks?
In the Edge Strength Profile, drag the blue edge strength line until it lies below the peaks, or decrease the value of the Minimum Edge Strength control.
Q: What should I do if the step finds edges in locations slightly different from where I expected them?
- Adjust the Kernel Size and Projection Width values until the profile shows peaks at the appropriate locations.
- Drag the yellow edge strength line in the profile until it lies below the peaks, or adjust the Minimum Edge Strength control.
