Spring 2002
CIS 6930-002 Image Based Biometrics
Time: 12:30pm to 1:45pm, Mondays and Wednesdays
Office Hours: 2pm to 3pm (Monday and Wednesday) (or any other time mutually agreed upon)
Location: ENG 003 (First of classes), ENB 313 (Rest of the semester)

Facilitator: Sudeep Sarkar


Goal: To investigate pattern recognition and computer vision techniques that can be used to identify humans from image data, be it video sequences or still frames.  What are the limitations of these techniques? How do you evaluate their effectiveness? Can information from different imaging modalities be combined to arrive at better performance? Can you identify humans at a distance? What are the ethical implications of this technology?

Impact on society: This technology has obvious impact on automated surveillance tasks. It can also be used to authenticate person to allow access of information remotely, e.g. web based financial transactions, automated teller machines, access to secure area or equipment, and so on.

Pre-reqs: Digitial Image Processing (CAP 5400) or Computer Vision (CAP 6415)

Scoring of Student Performance will be based on progress on project, presentations made to the class, and class participation. There will be no formal exams. There might be a few quizes. Tentatively:

       45% project (30% report + 15% presentation),

       15% discussion,

       20% Core technique notes,

       10% class participation,

       10% worksheets, project status reporting, project proposal etc.

Textbook: There is no standard textbook. Relevant papers will be provided or made available. A couple of reference texts: (i) Biometrics (A Jain, R Bolle, and A Pankanti Eds) (ii) Pattern Classification (Duda, Hart, and Stork)
