David Mulyono, Horng Shi Jinn, 2008, has introduced [Mulyono, 08] preliminary process to enhance the image quality worsened by light effect and noise produced by the web camera, then segment the vein pattern by using adaptive threshold method and matched them using improved template matching. The experimental result shows that even the image quality is not good, as long as the veins are clear and also with some appropriate process it still can be used as the means of personal identification.
