Abstract:

 For lacking of multifinger fingerprint segmentation algorithm to induct multifinger recognition engineering applications at present, it will increase the difficulties of finger recognition application. To satisfy the need of engineering applications, a new multi-finger fingerprint segmentation algorithm is proloosed.Distributions of X-projection, Y-projection and segmentation of projection of edge image are counted to get the coarse each finger position, and then the direction of main axis of each finger, X-projection, Y-projection and segmentation of projection of each region are computed to locate each fingerprint region. In experiment, 600 multifinger images, including different background light, hand gesture are tested by the proposed algorithm. Experimental results show that the algorithm can meet the need of engineering applications.   
