NISIR 7747: SlapSegII Analysis: Matching Segmented Fingerprint Images

The SlapSegII evaluation was performed to measure the current capabilities of four-finger slap segmentation algorithms to correctly segment fingerprints within a certain geometric tolerance of hand-marked ground truth data. The tolerances were based on matching studies conducted on a data sample of the 2-inch tall slap fingerprint data. In those matcher studies various tolerance limits were studied and the SlapSegII tolerance limits were selected to have a minimal effect on the matching accuracy.
