A New Touchless Palmprint Location Method Based on Contour Centroid
Palmprint image has been widely used in personal recognition system, and various techniques have been proposed to improve its performance. It is known that the recognition accuracy depends on the location effect to a great extent. In this paper, we proposed a new method in locating the central block of palmprint image, which makes use of the distance between corner points and contour centroid. This method aims to achieve a faster and more stable location on palmprint image. And it can tolerate the rotation of palmprint image in plane surface. This system consists of two parts: a novel device for touchless palmprint image acquisition and an efficient algorithm for palmprint location.
