Edge Score Threshold Minimum score to accept an edge. The score of an edge is returned by the Edge Score result. Search Parameters Show all edges found by the tool. Show Results Graphics Specifies if the graphics are drawn in the Vision Window. Region of Interest (ROI) Relative To Specifies the tool that will provide the input to this tool. The tool can be dragged from the Folder pane and dropped into this field.
Search Region Defines the Center, Radius, Rotation, Thickness, and Opening of the ROI. Tool Links Image Source Defines the image source used for processing by this vision tool. Advanced Properties Bilinear Interpolation Enabled Specifies if bilinear interpolation is used to sample the input image. By default, bilinear interpolation is enabled because it improves accuracy. Custom Sampling Step When enabled, the tool uses the user-defined sampling step instead of the default optimal sampling step to sample the region of interest from the input image. Projection Mode Projection mode used by the tool to detect edges.
Edge Filter Half-Width Width of the edge, in pixels, as it appears in the image. Sort Results Enabled Specifies if the results should be sorted. Object Definition Instance The result instance (numbered from 0).
