Abstract
The authors have developed a prototype miniaturized active vision
system whose sensor architecture is based on a logarithmically
structured space-variant pixel geometry. This system integrates a CCD
sensor, miniature pan-tilt actuator, controller, general purpose
processors and display. Due to the ability of space-variant sensors to
cover large work-spaces yet provide high acuity with an extremely small
number of pixels, space-variant active vision system architectures
provide the potential for radical reductions in system size and cost.
The authors describe a prototype space-variant active vision system
which performs tasks such as moving object tracking and functions as a
video telephone. The potential application domains for systems of this
type include vision systems for mobile robots and robot manipulators,
traffic monitoring systems, security and surveillance, and consumer
video communications
