Motion analysis for face capturing

Face recognition is one of the most suitable biometric methods for supporting systems that require high security. The success of a face recognition system involves more than just the comparison algorithm. Face data acquisition is the first step towards developing face recognition systems. The accuracy of a face recognition system greatly depends on the face data acquired. This paper proposes the head-nodding method for face capturing using motion analysis. By analyzing the head-nodding motion of the user, the head-nodding method captures face images with consistent orientation to support face verification systems. In this paper, the design and implementation of the head-nodding method is presented. Preliminary experimental results are also presented.
