Embedded image processing on the focal plane promises high image signal
quality and fast, compact and low-power information extraction for machine
vision applications. Over the past decade, the promise of improved signal
quality has been achieved, and we are now able to buy cheap ~60dB CMOS
high-resolution imagers. The goal of fast, compact and low-power
information extraction is, however, still elusive. Problems with
inefficient chip area usage, incompatible algorithms and high power
consumption, typically high speed digital, have limited the success on
this front.
We have developed a technique that attempts to provide all these promises
using digitally programmable analog computation. Our approach remains
compatible with standard computer vision interfaces by preserving the
image resolution and scanning format, while in parallel extracting various
spatiotemporal features from images. Furthermore, our systems performs
greater than 10 GOPS/mW, albeit at ~6 bits of resolution, at many
thousands of frames per second. We use a block parallel, mixed signal
MIMD architecture with low silicon footprint for this purpose.
I will present the evolution of our General Image Processing (GIP) chip
and show its potential power as an Adaptive Computational Sensor (ACS) for
synthetic imaging. I will describe the processing architecture and
demonstrate its application to spatiotemporal filtering and line segment
orientation detection. I will also describe a biomorphic chip for the
adaptive control of biped locomotion. I will show some sensory adaptation
examples.
Ralph Etienne-Cummings received his B. Sc. in physics, 1988, from Lincoln
University, Pennsylvania. Complete his M.S.E.E. and Ph.D. in electrical
engineering at the University of Pennsylvania in 1991 and 1994,
respectively. Currently, Dr. Etienne-Cummings is an assistant professor of
electrical and computer engineering at the Johns Hopkins University,
Baltimore, MD. His research interest includes mixed signal VLSI systems,
computational sensors, computer vision, neuromorphic engineering, smart
structures, mobile robotics and robotics-assisted surgery. He is a
recipient of the NSFUs Career Development and ONR's YIP Awards.
