RESEARCH AND
DEVELOPMENT IN COMPUTER IMAGING SYSTEMS
My research and development in the area of computer imaging systems
started in 1986 when I was hired into the Imaging R&D unit of the IBM Toronto Laboratory. My first project involved
the development of enhancement and restoration techniques for the processing of 8-bit gray images on PCs and PS/2 machines. In
1989 working as part of the IBM’s
Centre for Advanced Studies (CAS)
I collaborated with the PAMI group of University of Waterloo
on the development of face recognition system. This system included feature
extraction based on expert-assisted feature selection, spatial feature
measurement and representation, feature information compression and
organization, search procedures and pattern-matching techniques. Another
project on which I worked while in CAS
was the calibration of colour monitors using the CIE standard. In this
project we developed a number of models which lead to accurate colour display for a large range of luminosities. We also
studied colour calibration of scanners and printers.
After leaving IBM
I had the opportunity to get back to computer imaging systems in 1997 when I
was hired by I-Image Medical
Technologies Inc., Montreal
to design and develop a pattern recognition program which measures and analyses
eye blood vessels in the assessment of an ophthalmic patient before and after
medical or surgical interventions.
All this work on computer imaging systems was
published in journals or technical reports and presented at various
conferences.
