Completed projects

04/2002-4/2007: Fingerprint recognition technologies for BIO-key (R) International, Inc.

I quit the company in April 2007, and currently comply with the one-year non-compete agreement with BIO-key.

February 1st, 2008 update: This personal Web page is developed for professionals and for those who seeks for professional algorithm designers. However, as an outsider's email brought my attention to today's Yahoo!Finance message board posts referring to my page, I choose to omit information about my BIO-key projects, to avoid any violation of the agreement.

For those who visits this page to collect information about BIO-key -- rest assured that company's engineers and scientists are indeed capable of supporting and improving my input, whatever of it remains in use.

10/2001-2/2002: Fingerprint recognition algorithm for Fingerprint Verification Competition 2002.

The international Fingerprint Verification Competition takes place every other year. This is a major event in biometrics. The organizers benchmark fingerprint recognition technologies. 48 teams signed-in initially for FVC 2002.  The final competition was between 31 participants (mostly industrial, with 6 academic teams, another independent developer and me).

My ranking is here: the official table of average results, ordered by perfomance in high security domain.

I got into the medal table, achieved the sixth place by average EER and the third place in the world in the major biometrical domain, performance at low false accept levels: in average on all databases in both False reject rate at Zero false accept and False reject at 0.1% false accept I was behind only Bioscrypt and an anonymous (Bioscrypt's clone?). 

The algorithm outperformed industrial monsters like SAGEM - the winner of FVC 2000 - and many other formal "industry leaders", despite a bug in the executables inflated all the average error indices on four databases by 0.5% (after all, it was just a five months effort to restore/improve the algorithm abandoned in 1998!).

After bug fixes and few parameter adjustments, on high quality FVC 2002 databases it operated at the same error levels as Bioscrypt (the winner of FVC 2002); on more realistic databases it was better. For instance, in 2002 Bioscrypt published its EERs for FVC 2000 databases (they were significantly better than the winning numbers of Sagem, and best published so far). Few months later, the error rate of my algorithm on these databases was ~50% less in average than Bioscrypt's, with uniformly better performance on all four databases.

05/2001-10/2001: Text detection from a video stream (for BBN Technologies, with Prem Natarajan).

04/2001-05/2001: Language identification from [spoken] speech utterances (for BBN Technologies, with Prem Natarajan).

8/1999-1/2001: Forecasting of electric power demand (medium-term spatial forecasting of electric loads on Long Island for LIPA/KeySpan, with Prof. E.Feinberg)

6/2000-11/2000: Technology for comparison of speech recognition engines in noisy environments (for Symbol Technologies).
