Abstract

A 2-D median based filter for real-time video signal processing is presented. The device is able to remove impulse and missing line noise in real-time without blurring sharp video images. A prototype using 75 standard TTL chips was realized on one single speedwire prototype board of size 17x30 cm² and its structure is suitable for VLSI implementation. The statistical performance of the non-linear filter was also investigated and compared with standard 2-D median filters. It is shown that the filter has superior characteristics to its median based counterparts while the hardware implementation is much simpler.
