Abstract
The present teachings provides a palm vein identification device and a palm vein identification method. The method may comprise: acquiring a target palm vein image of a user; extracting a region of interest (ROI) from the target palm vein image of the user; acquiring feature data corresponding to the ROI, wherein the feature data are obtained by binarization processing; and comparing the feature data corresponding to the target palm vein image against feature data corresponding to a registered original palm vein image to perform identification on the target palm vein image of the user, wherein the feature data corresponding to the registered original palm vein image are obtained by calculation in advance.
