ABSTRACT:
A system for locating at least one object within an intensity image is disclosed. The system includes means for analyzing the intensity image with at least two different edge detectors to detect a multiplicity of edges oriented in at least two directional ranges. First comparing means is provided for comparing information representative of detected edges angularly oriented in a first directional range and information representative of detected edges angularly oriented in a second directional range. Means for selecting at least one foreground region in the intensity image is also included. The detected edges in the selected foreground region are angularly oriented substantially in accordance with a target orientation.
