Show Results Graphics Specifies if the graphics are drawn in the Vision Window. Tool Links Image Source Defines the image source used for processing by this vision tool. Region of Interest (ROI) Offset Specifies the center and rotation of the ROI. X, Y, Degrees. 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 Area Defines the height and width of the region of interest. Advanced Properties Conformity Tolerance Sets the maximum local deviation between the model contours and the contours detected in the input image. Allows a selection of Default or a fixed Tolerance within a range. Contour Detection Specifies the configuration of the contour detec- tion parameters. Contrast Polarity Sets the type of polarity accepted for object recog- nition. Contrast Threshold Sets the minimum contrast needed for an edge to be detected in the input image.
Instance Ordering Sets the order in which the instances are pro- cessed and output Minimum Clearance When enabled, sets the minimum percentage of the model bounding box area that must be free of obstacles to consider an object instance as valid.
