Modified 2D median filter for impulse noise suppression in a real-time system

A new modified 2D (3*3) multi-shell median filter (MMMF) for restoration of images corrupted with impulse noise is presented. This filter can not only reduce impulse noise but alleviate missing line errors. The hardware of MMMF can be easily implemented using standard TTL ICs. In fact, we realize the circuit by the Field Programmable Gate Array (FPGA). This novel median filter can be used in a real time system for noise suppression.<
