SlapSeg III Evaluation

Neurotechnology's slap fingerprint segmentation algorithm has been judged by NIST as the most accurate among the SlapSeg III 2 inch category participants.

What is SlapSeg III?

SlapSeg III Evaluation is a NIST-run public test of automated slap fingerprint segmentation algorithms. Output from the tested automated algorithms is compared to output from a human examiner and analyzed for similarity.

See SlapSeg III official page for more information.

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.

There are 4 categories in the SlapSeg III evaluation:

  • 2 inch are scanned images of inked tenprint card slaps. Neurotechnology evaluation results are presented below.
  • 3 inch are live scan images captured using devices with a scanning surface of 3 inches. Neurotechnology plans to participate in this category.
  • 5.5 inch are half palm (upper palm) live scan images. Neurotechnology plans to participate in this category.
  • 8 inch are full palm live scan images. Neurotechnology plans to participate in this category.

2 Inch Category

These comments provided by Neurotechnology are based on the submission results, published on March 10, 2021.

Currently there are 6 companies participating in the evaluation. Our latest submission was Neurotechnology+0005. The submitted algorithm is available in MegaMatcher 12.2 SDK and VeriFinger 12.2 SDK.

Segmentation accuracy is measured by percentage that at least 8 fingers were segmented correctly. According to this accuracy measurement our algorithm is the most accurate among the participants. Also our algorithm is the second fastest algorithm in the 2 inch category, while the faster contender showed much worse accuracy. Overall Neurotechnology+0005 showed the best speed and accuracy combination in this category.
