Interest factor controlled compression of imagery

Imagery, also when compressed, require relatively large bandwidth. Homeland defense applications will use a large number of unattended image sensors which will generate enormous amounts of raw data. This paper deals with transmission aspects of scenes containing combinations of potentially interesting objects and the background they are appearing in. The purpose of interest factor controlled compression (IFCC) is to represent the background areas using a coarse representation which does not use an excessive amount of bandwidth, while areas that are assumed to contain interesting objects receive better treatment in terms of image quality and error resilience. Results of IFCC compression of infrared imagery are shown.
