Real-time face detection with MPEG-4 codec LSI for a mobile multimedia terminal

We propose an intelligent easy-operating human-machine interface incorporating face detection technology for a mobile multimedia terminal. We have developed a face detection algorithm which works on the resources of a mobile phone. This algorithm is robust in outside fields, and simultaneously works with MPEG-4 Simple Profile Level 1 encoding and decoding on an MPEG-4 codec LSI for a mobile videophone. This enables more intelligent interfaces in visual communication such as IMT-2000 videophone services.

Profile face detection using block difference feature for automatic image annotation

We propose a new profile face detection system for automatic image annotation. For personal images, profile face detection is required because faces turn in different directions. To reduce the numerous false detections seen in previous approaches, we propose a block difference feature. The experiments we describe show the successful outcome of this strategy.
