Enhancing Imagery to Improve the Visibility of Detail

Abstract

Imagery from surveillance sensors is often not suitable for immediate viewing, because the number of grey levels or colours used is much larger or smaller than the number available on the display device. This Report considers some old and new techniques for making imagery ready to view, so that both broad features and fine detail are visible. The basic techniques often give poor results when they encounter the peculiarities of particular sensors or scenes; in these cases variations are available that overcome the problems at a cost in computing time. Examples of the application of techniques and variations to airborne sensor imagery are given.
