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 Connectivity Specifies the minimum number of connected edges required to generate a point hypothesis. Contrast Threshold Defines the minimum contrast needed for an edge to be detected in the input image. Interpolate Position Mode Sets the mode used by the Point Finder to com- pute a point hypothesis Positioning Level Sets the configurable effort level of the entity-pos- itioning process.
