SlapsegII has been superseded by SlapsegIIIBegin: April 7, 2009
SlapSegII is now being performed as an ongoing evaluation. Participants can submit to have segmentation algorithms evaluated by completing a SlapSegII Application . The SlapSegII evaluation Plan provides all the details on the evaluation and how to submit software. Upon completion of testing results will be posted in SlapSegII Results . Participants are limited to testing an algorithm every 90 days from the date the previous successful algorithm started testing (dates will be posted in SlapSegII Results).
SlapSegII Analysis Document
November 22, 2010
This study compared the matching accuracy of hand-marked segmentation and automated segmentation algorithm results to examine the effect of automated slap fingerprint segmentation errors on matching accuracy.

Draft Evaluation Plan for SlapSeg IIJuly 23, 2008
This new version of the evaluation plan contains the details on how a successful segmentation will be determined for 2 inch slap image data and a few clarifications on the 3 inch success measure. The following edits were made to the document:
- section 188.8.131.52 - Added maximum width x height limits for 2 inch slaps data
- section 4.9.1 - Added text stating the ground truth for 2 inch slap data used rectangular boxes.
- section 6.1 - Added formulas used to determine successful segmentation of 3 inch slap data.
- section 6.2 - Added 2 inch success measure.
June 13, 2008
Contains 2 minor changes to section 4.9.1:
- States that 0 degrees for 2 inch rotated images is vertical,
- Reorganized so finger definitions appear before examples of output file format.

Here is the updated Slap Fingerprint Segmentation Evaluation II Draft Testing Plan as of June 3, 2008 in pdf format.
May 13, 2008:
In 2004, NIST conducted a fingerprint slap segmentation study  to assess the state-of-the-art in fingerprint segmentation technology. Given the development of new technology it has become necessary to reassess the current state-of-the-art of segmentation algorithms. SlapSegII will give providers of this technology the opportunity to participate multiple times as their technology improves and compare their results to previous results on a fixed standard database. The SlapSegII testing strategy, evaluation data, and measure of successful segmentation are discussed in detail in this testing plan.
