Experimental results show that the algorithm can effectively extract the skeleton and preserve the edge of vein images and restrain the over-segmentation phenomenon in the watershed at the same time.

We proposed a new method to enhance the contrast of the finger-vein image.

Primary analyzing and studying palm vein pattern recognition system,this paper will offer some hardware implementation solutions based on our research,including how to select CCD vidicon,how to design lighting system etc,design a palm vein scanning experiment device,accomplish setting up the whole palm vein pattern recognition system and acquire the clear palm vein image.
