Abstract :
A robust distributed architecture for real-time object-based processing is presented for tasks such as object size, centre and count determination. This approach uses the input image to enclose a feedback loop to realize a data-driven pulsating action. Outlined is the top level design for hardware implementation in a standard CMOS technology.
