Abstract
This paper proposes a hardware-based line feature enhancement approach that uses a palmprint acquisition device fitted with a time-sharing light source. When capturing images, two lamps of the light source can be lit in turn, producing two, differently lit images. As the two lamps light the inner surface of the palm from different directions, they capture images with different lines enhanced. By fusing the two images with a nonlinear method, we can produce a palmprint with much clearer line features. Our research will focus on improving this device and integrating it into a functional palmprint verification system.
