Banner PresencePLUS P4 EDGE 1.3 Series - Manual (Page 109)

Description Field
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 Min Width
free from additional transitions or the end of the ROI before the edge is
recognized.
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.
The bottom graph, Edge Strength, represents the change in gray scale along the Edge tool.
