High-Speed Facial Recognition Using Log-Polar Transformation

Abstract

Log-Polar transformation is an approximate model of human vision. If using it to recognize human faces, a reference point for the transformation is necessary, and the position of the reference point influences the recognition accuracy directly. However, it is difficult to extract an appropriate reference point from an image automatically. This paper proposes a face recognition method that detects the face center point as a reference point for Log-Polar transformation automatically. It is easier than before to recognize the faces by using Log-Polar transformation with the propose method.
