PTZ camera assisted face acquisition, tracking & recognition

摘要: Face recognition systems typically have a rather short operating distance with standoff (distance between the camera and subject) limited to 1~2 meters. When these are used capture face images at larger (5~10 m), resulting contain only small number of pixels on region, in degradation performance. To address this problem, we propose system consisting one PTZ two static cameras acquire high resolution up 10 We novel calibration method based coaxial configuration cameras. also use linear prediction model control mitigate delays image processing mechanical motion. The proposed has acquisition effectiveness test. Experimental results video data collected ranging from 5 meters 20 different subjects as probe 10,020 gallery shows 96.4% rank-1 identification accuracy compared 0.1% conventional using state-of-the-art matcher.
