Abstract :
This paper describes the architecture of adaptive space-variant sensors with Cartesian topologies. Besides their multiresolution output, reconfigurable sensors can be upgraded to generate additional data to be processed at higher level modules of the vision systems, making it possible to unload the processing stages of certain tasks, without penalty in time or significant addition of hardware. A synthesizable implementation of these sensors, based on off-the-shelf FPGAs and CCD cameras is also described
