发明名称 Method for forgery recognition in fingerprint recognition by using a texture classification of gray scale differential images
摘要 In a method for forgery recognition in the fingerprint recognition, at first an image sequence is captured, which comprises a plurality of images of the fingerprint to be recognized. From at least two images capturing a texture captures a differential image. The texture will be compared with a predetermined texture in order to determine whether the captured image sequence comes from a real finger or from an imitation.
