In this paper,a new algorithm based on ridgeline tracking is proposed.It directly processes on the gray image,tracks the vein ridgeline along the texture,and overcomes the disadvantages of image disposing.Locally reinforce the image,locally set the region value.Finally,we get a image of hand vein ridgeline.This algorithm effectively decreases the cost of computing,avoids the info losing when setting the region value.Compared with the traditional method,it has remarkable advantage in speed,meantime keep a good veracity.
