Vision-based face understanding technologies and their applications

We have developed a group of vision-based face understanding technologies called OKAO Vision (OKAO means face in Japanese) including face detection, facial feature point detection, face recognition and facial attribute estimation. Our face detection technology can detect both frontal and profile faces rotated to any angles. Facial feature point detection, face recognition and facial attribute estimation are based on a common architecture: using Gabor wavelet transform coefficients as feature values and use SVM as classifier. Our experiments show that this architecture is very powerful. In this paper, we explain the key technologies of OKAO Vision and how these technologies are used in applications for entertainment, communication, security and intelligent interfaces.
