### SlapsegII has been superseded by SlapsegIII

**Begin: 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**

NISTIR 7747	SlapSegII Analysis: Matching Segmented Fingerprint Images

**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.**

### SlapsegII Results Document

**February 17, 2009**
SlapSegII_NISTIR_7553.pdf

**This is the final report for the Slap Fingerprint Segmentation Evaluation II. Any edits or changes to this report will be noted on this page.**

### **Draft Evaluation Plan for SlapSeg II**

**July 23, 2008**
SlapSegII_testplan_072208.pdf

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 4.8.1.1 - 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**

SlapSegII_testplan_061208.pdf

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.
                  

**June 3, 2008**

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 [1] 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.
