Abstract
Current still image and video systems are typically of limited use in poor
visibility conditions such as in rain, fog, smoke, and haze. These conditions
severely limit the range and effectiveness of imaging systems because of the
severe reduction in contrast. The NASA Langley Research Center s Visual
Information Processing Group has developed an image enhancement technology
based on the concept of a visual servo that has direct applications to the
problem of poor visibility conditions. This technology has been used in
cases of severe image turbidity in air as well as underwater with dramatic
results. Use of this technology could result in greatly improved performance
of perimeter surveillance systems, military, security, and law enforcement
operations, port security, both on land and below water, and air and sea
rescue services, resulting in improved public safety.
