FUTURE TECHNOLOGY 
The developments in the field of advanced digital video 
techniques, high definition video system and ultra high speed 
V LSI devices for memory , and several computational and 
and processing functions will ennance the capability of video - 
rate image processing systems manyfold ^ in the coming years.
