1. A system for placing and sizing on a Graphical User Interface (GUI) display at least one of Locators and Detectors comprising one or more processors implementing the steps of: a GUI screen image view of an object derived from a vision sensor having a field of view in which the object is in relative motion thereto and a plurality of captured image frames of the object within the filed of view, the image view being accessible by a GUI cursor; an edge detection process that determines and analyzes detectable edges in the screen image view and stores edge information; a selector that allows a user to select either a (a) Locator or (b) a Detector based upon a predetermined analysis tool for placement on the image view; and an automatic placement process that uses the edge information to place the selected (a) Locator or (b) Detector at a position on the image view upon which the cursor points with a size that is determined based upon a location of adjacent edges of the object image view.
