Title: Iris feature detection and sensor-based edge detectionApplicant: Hewlett Packard Development Co (US); Perner Frederick A (US)Patent number: WO2006009837Publication date: 26 January 2006
An iris feature detector includes a reflexive eye movement source; a multiple image sensor; a controller; and a processor. The controller causes the eye movement source to cause rapid eye motion, and the sensor to capture first and second iris images over a time interval in which only an iris can move in the first and second images. The processor determines differences between the first and second images. The sensor may be integrated with the processor. The integrated sensor/processor is not limited to iris feature detection, and may be used for edge detection for machine vision and other applications.
