  4. Project Overview: This technology is fairly new, so we propose: • Research methodology for an “efficient training” of the CogniMem Neural processor. • Concurrently, develop “reproducible procedures” for a "high-level confidence" for “Facial Biometric recognition” application in a static physical environment. • As needed, create hardware interface with the device; develop software for a particular application.

  13. Approaches: • Phase 1 (Completed) • Create a “controlled environment” to characterize the Biometric limits of the CogniMem device with respect to known environmental changes (more elaboration is just a sec). • “Lesson learned “ comprehensive review of result (in-progress). • Phase 2 • With lesson learned in Phase 1: Will implement a controlled-group “open environment” characterization/testing of the device (more elaboration is just a sec). • Phase 3 • Verification and “variable-environment” testing of the controlled-group (8 individuals) to the general population  False-Positive • Control group (thru external facial manipulation) to deceive & create “Positive  Unknown” identification

  14. Phase 1: Results • Result Discussion: • Lighting Variation Effects • External Facial Accessories Variations Effect • Facial Changes Effects • Facial Expression Effects

  15. Phase 1: Lesson Learned • Perform training with “sufficient lighting” • “Zoom-in” ROI size to facial contour. • If possible, set camera configurations to “manual mode” (i.e. shutter speed, gain, etc.) • First neuron committed should be on the background environment. • CogniMem device is somewhat unstable. - Froze 3X (after 10, 2 & 40 minutes of operation). - Uncontrolled neuron assignment.

  16. What’s next?Phase 2 & Phase 3 • Phase 2 • With lesson learned in Phase 1: Will implement a controlled-group “open environment” characterization/testing of the device (more elaboration is just a sec). • Concurrently, research cause for the • CogniMem to “freeze” • Uncontrolled neuron assignment • USB port assignment erratic

  17. What’s next?Phase 2 & Phase 3 • Phase 3 • Verification and “variable-environment” testing of the controlled-group (8 individuals) to the campus general population  False-Positive • Control group (thru external & facial manipulation) to deceive & create “Positive  Unknown” identification

  18. Problems (Yes, we have them): • Hardware & Software • CogniMem to become unresponsive • Uncontrolled neuron assignments (without any keyboard or mouse activity); normally happens right after the CogniMem device becomes unresponsive. • USB port assignment erratic

  19. End of Semester Project Goals: Our projected goals are to: • Develop efficient training methodology of the CogniMem device. • Develop “reproducible procedures” for a "high-level confidence" Biometric recognition training. • Have a working model for a static Facial Biometric identification that is reliable. • Hopefully, find solutions to the hardware and software problems we are experiencing to have a more stable system. • EE496: Lay the ground-work for a “dynamic” Facial/Body Biometric follow-on project.
