Banner PresencePLUS P4 COLOR Series - Manual (Page 163)

A bright-to-dark transition has a negative edge strength value, and a dark-to-bright transition has a positive edge
strength value. When the Edge Strength level is adjusted, both the negative and positive green dotted lines will adjust
together.
Filters
Description Field
Increases in increments of 4 pixels (for example, 1, 5, 9, 13, ...) up to the total
FOV size. Some things to note: ROI Width
• Narrow ROIs execute faster but could miss the edge.
• Wide ROIs are more consistent but don't execute as fast.
• The ROI must be 13 pixels or wider to calculate the rotation of a part.
Runs a rolling average along the ROI length. It filters out sharp changes in the
edge profile. Smoothing
Note: A high filter number may miss the edge of a narrow line.
Filters out small spike-of-intensity changes, and narrow dark or bright bands. It
determines the distance (in pixels) before and after an edge that must be free from
additional transitions or the end of the ROI before the edge is recognized. Min Width
Note: A high filter number may miss the edge of a narrow line.
Determines the sub-pixel resolution, which increases the resolution of the tool,
and increases the inspection time. Sample Rate
1. 1-pixel resolution
2. 1/2-pixel resolution
3. 1/3-pixel resolution
4. 1/4-pixel resolution
Object Width
Object Width filters out objects and spaces that are smaller than the minimum and larger than the maximum values
specified.
