Abstract :
Infra-red images have proved extremely useful in obtaining synoptic views of sea-surface temperatures. This paper describes several techniques for displaying and processing such pictures. These include a method to automatically assign the grey-levels in the displayed pictures to minimize information loss. Also discussed are techniques to reduce random uncorrelated noise and enhance oceanic features such as fronts.
