ABSTRACT:
A system and a method for segmenting slap fingerprints is described. The method includes providing a print image, optionally pre-processing the print image, detecting at least a plurality of image components of the print image, determining at least one segmentation boundary for the print image, and computing the convex hull of the image components. The orientation, relative orientation and placement of the image components are detected. The zone lines of each component are found and zone areas are defined. The components under the top component of each zone are deleted. The finger numbers are assigned in accordance with the anchor print component, the geometrical relationship among the components. The slap print image is segmented in accordance with the segmentation boundary and its neighboring boundaries.
