Finger-vein structure description method with B-spline
摘要
Abstract
The conventional methods for finger-vein structure description could not fully describe the distinct and steady line-structures of finger-vein.Therefore,a finger-vein structure description method based on B-spline was proposed.The new method obtained the coordinate set of all target points on every finger-vein branch by using line scanning operation on thinned finger-vein images.A B-spline function was used to fit the curves of finger-vein branches.The control-point coordinates of every B-spline curve were gained,and they were used to describe the line-structures of finger-vein.Experiments show that the new method can availably describe line-structures of finger-vein with little description error and small storage space requirements.Furthermore,this method can improve the recognition rates of finger-vein.关键词
