Low-power always-on face detection, tracking, recognition and/or analysis using events-based vision sensor

摘要: Techniques disclosed herein utilize a vision sensor that integrates special-purpose camera with dedicated computer (CV) computation hardware and low-power microprocessor for the purposes of detecting, tracking, recognizing, and/or analyzing subjects, objects, scenes in view camera. The processes information retrieved from using included sends “events” (or indications one or more reference occurrences have occurred, and, possibly, associated data) main processor only when needed as defined configured by application. This allows general-purpose (which is typically relatively high-speed high-power to support variety applications) stay (e.g., sleep mode) most time conventional, while becoming active events are received sensor.
