Slap Fingerprint Segmentation Evaluation (SlapSeg) III is a public test of automated slap fingerprint segmentation algorithms. Fingerprint segmentation is the act of separating or segmenting an image of the friction ridge structure of the hand into individual images of the upper-most finger joints, known as distal phalanges. In SlapSeg III, output from automated algorithms is compared to output from a human examiner and analyzed for similarity.
SlapSeg III is the latest in a long history of slap fingerprint segmentation evaluations conducted by the NIST Image Group. Prior evaluations include SlapSeg II (2008–2018) and SlapSeg 04 (2004–2005). These evaluations produced a number of relevant documents:
