Face detection using a time-of-flight camera

Abstract

We adapt the well-known face detection algorithm of Viola and Jones to work on the range and intensity data from a time-of-flight camera. The detector trained on the combined data has a higher detection rate (95.3%) than detectors trained on either type of data alone (intensity: 93.8%, range: 91.2%). Additionally, the combined detector uses fewer image features and hence has a shorter running time (5.15 ms per frame) than the detectors trained on intensity or range individually (intensity: 10.69 ms, range: 5.51 ms). © 2009 Springer Berlin Heidelberg.
