Face Recognition Prize Challenge 2017

Ongoing
Results From June to September 2017, NIST evaluated 41 face recognition algorithms from 16 developers. The algorithms were applied to datasets of 2D still photographs in two ways: verification of “wild” photojournalism and social media images, and identification of faces from surveillance videos

Ongoing
Instructions on getting FERET database Introduction Department of Defense (DoD) Counterdrug Technology Development Program Office sponsored the Face Recognition Technology (FERET) program. The goal of the FERET program was to develop automatic face recognition capabilities that could be employed to

Face Recognition Vendor Test (FRVT)

Ongoing
Ongoing FRVT Activities FRVT: FACE MASK EFFECTS NIST has published NISTIR 8331 - Ongoing FRVT Part 6B: Face recognition accuracy with face masks using post-COVID-19 algorithms on November 30, 2020, the second out of a series of reports aimed at quantifying face recognition accuracy for people

Face in Video Evaluation (FIVE)

Ongoing
2024-01-23 FIVE 2024 Announced! The Face in Video Evaluation (FIVE) 2024 is being conducted to assess the capability of face recognition algorithms to correctly identify or ignore persons appearing in video sequences – i.e., the open-set identification problem. For more information, please visit the

Facilitating the Development of Modular Data Models in Materials Science

Ongoing
Development of Data Models This project is convening experts with the goal of developing foundational data types and domain-specific data models to address common modeling, synthesis and measurement techniques. The existence of such data models will facilitate the adoption of the Materials Data

Farad and Impedance Metrology

Ongoing
The primary facility for connecting the U.S. legal system of electrical units to the international system of units is the NIST calculable capacitor, with which the measurement of capacitance is effectively achieved through a measurement of length. Both the calculable capacitor and the chain of high

Fast Tenprint Capture

Completed
September 2007: Framework We presented the framework regarding the evaluation of 3-D fingerprint image capture devices at the Biometric Consortium Conference at Baltimore. You may download the presentation. January 2008: Meeting We had a meeting with Dr. Stanley Erickson, who is the sponsor

Fatigue in Silicon

Ongoing
It has long been thought that bulk silicon is immune to fatigue. We present contrary evidence by demonstrating severe fatigue in macroscale specimens. Cracks are produced during cyclic loading of monocrystalline silicon plates with a 3 mm radius sphere indenter mounted onto a universal testing

Fatty Acids in Human Serum and Plasma Quality Assurance Program (FAQAP)

Completed
Interlaboratory comparison studies of the FAQAP focused on the measurement of 24 fatty acids in selected serum and plasma matrices. Frozen or freeze-dried serum or plasma samples were sent to laboratories for analysis together with control materials. Results were returned to NIST for data evaluation

Fault Detection and Diagnostics for Air-Conditioners and Heat Pumps

Ongoing
Objective Develop fault detection and diagnostic (FDD) methods and measurement tools to ensure air conditioners (ACs) and heat pumps (HPs) perform as designed throughout their lifetime and develop a testing and rating methodology to assess relative merits of different commercial FDD products

Femtosecond Nonlinear Optical Spectroscopy of Nanoscale Materials

Ongoing
The purpose of this project is to develop and refine spectroscopic techniques based on nonlinear optics for the study of novel materials. Measurements that isolate the nonlinear response are often better able to uncover physical processes that, in the linear response, are subtle and hard to isolate

Femtosecond-Laser Frequency Combs for Optical Clocks

Ongoing
The self-referenced optical frequency comb, which our NIST/University of Colorado collaboration first demonstrated in 1999, ushered in a revolution in optical frequency metrology. The frequency comb made it possible to directly count optical cycles with femtosecond resolution using a compact and

Fiber Sources and Applications Background Information

Ongoing
NIST has been a world leader in lasers since the technology's development in the early 1960s, a tradition continued when NIST scientist John L. Hall shared the 2005 Nobel Prize in physics for his part in the invention of the optical frequency comb. The output of a comb is a brief broadband pulse
