Banner PresencePLUS P4 COLOR Series - Manual (Page 147)

Description Field
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
Edge Tool Results
The Results field returns the following:
• X,Y coordinates of the current edge. The origin (0,0) is the upper-left corner of the screen.
• A Edge Number field for selecting an edge to analyze.
• Total number of bright-to-dark and dark-to-bright edges, depending on the Polarity option in effect.
Graph Tab
When Edge Strength is selected, the Graph tab appears on the tool window. The graph for the Input tab overlays both
the edge strength graph and the edge profile. In the Graph tab, the edge profile graph and the edge strength graph are
separated for easier viewing.
The top graph, Edge Profile, represents the absolute gray scale level across the Edge tool.
