Precise eye detection from image sequences

Automatic face location in complex scenes is extremely challenging in human face recognition system. The accuracy of the location is also a critical factor to the recognition performance. This paper presents a scheme to accurate eye detection from face sequences. After detecting the preattentive features by using the Gaussian steerable filter, face models are investigated to locate the whole face and the facial features such as eyes, nose and mouth. From the positions of eyes detected roughly, an approach to the precise detection of eyes is proposed, which is implemented with orientation calibration and phase registration. Because face is almost rigid object in image sequences, the direct registration can then work quite well. With the registered face sequences the precise eye positions is obtained.
