一种新的基于主线的掌纹识别算法，利用不规则的几何形状，以获得有效的掌纹区域，从而降低了影响大噪声；不仅结构特点，而且内涵信息被包括在最后

提取的主要线，提供了很多

掌纹识别的充分线索-a novel palmprint

recognition algorithm based on principal lines: a new

irregular geometrical shape was employed to get valid

palmprint region, which decreased the influence of

large noises　not only structure feature, but also

intension information were included in the final

extracted principal lines, which provides much

sufficient clues for palmprint recognition
