Analysis, Comparison, and Assessment of Latent Fingerprint Preprocessing

Author(s)
Haiying Guan, Paul Y. Lee, Curtis L. Lamp, Andrew M. Dienstfrey, Mary F. Theofanos, Brian C. Stanton, Matthew Schwarz
Latent fingerprints obtained from crime scenes are rarely immediately suitable for identification purposes. Instead, most latent fingerprint images must be

Calibration of Time-interleaved Errors in Real-time Digital Oscilloscopes

Author(s)
Jeffrey A. Jargon, Chihyun Cho, Joo-Gwang Lee, Paul D. Hale, Peter J. Jeavons, John B. Schlager, Andrew M. Dienstfrey
A novel method is proposed for the calibration of channel mismatch in a time-interleaved real- time digital oscilloscope (RTDO). A simple simultaneous nist

Analysis for Dynamic Metrology

Author(s)
Andrew M. Dienstfrey, Paul D. Hale
Diverse measurement contexts require estimates of time varying quantities. Ideally the measurement device responds to signal variations significantly more

A New Metric for Latent Fingerprint Image Preprocessing

Author(s)
Mary F. Theofanos, Andrew M. Dienstfrey, Brian C. Stanton, Haiying Guan
Although fingerprint recognition is a well-studied area, forensic fingerprint preprocessing based on computational theory is still a relatively new domain in

Preface

Author(s)
Andrew M. Dienstfrey, Ronald F. Boisvert

Traceability of high-speed electrical waveforms at NIST, NPL, and PTB

Author(s)
Paul D. Hale, Dylan F. Williams, Andrew M. Dienstfrey, Chih-Ming Wang, Jeffrey A. Jargon, David Humphreys, Matthew Harper, Heiko Fuser, Mark Bieler
Instruments for measuring high-speed waveforms typically require calibration to obtain accurate results. The national metrology institutes of the United States

A statistical study of de-embedding applied to eye diagram analysis

Author(s)
Paul D. Hale, Jeffrey A. Jargon, Chih-Ming Wang, Brett Grossman, Matthew Claudius, Jose Torres, Andrew M. Dienstfrey, Dylan F. Williams
We describe a stable method for calibrating digital waveforms and eye diagrams using the measurement system response function and its regularized inverse. The
