In a sixteen-year
career at Honeywell Systems and Research Center, Mr. Fant created
and directed key programs and contracts that led the Signal and
Image Processing group to preeminence in the nation in real-time
automatic target recognition. Other programs included medical
imaging, industrial inspection and image generation. Mr. Fant
is the co-inventor of Computer Generated Synthesized Imagery
(CGSI), which generates photo-realistic scenes in real-time from
libraries of photographic images, by warping each into place
and blending them together. In 1982 Mr. Fant received the H.
W. Sweatt award, Honeywell's highest award for technical achievement,
for his invention of a unique digital-image warping algorithm
developed for CGSI.
In October,
1990 Theseus Research Inc. was founded to provide consulting
in the design and implementation of real-time image processing
systems and to pursue applications of ongoing research into
the theory of computers. The primary accomplishment of Mr.
Fants consulting activity was the implementation of the prototype
L-VIS system for Princeton
Video Inc. This is the system that puts the yellow first-down
line on the football field, and that inserted the virtual advertisements
behind the batter in the 2001 World Series.
In January,
1996 Theseus Logic was spun out of Theseus Research to commercialize NULL
Convention Logic (NCL), a direct result of
Mr. Fants research in the theory of computers. NCL is an expressively
complete logic that is ideal for designing and implementing
clockless, logically determined, digital electronic circuits
and systems. Theseus Logic continues to commercially develop NCL.
Mr. Fant has returned to Theseus Research
to continue developing and commercializing new technologies
