Abstract
Fast pipelined CMOS integrated circuit implementation of the FIR Median Hybrid filter has been designed. The filter structure combines linear averaging subfilters to a median operation in a way that leads to a very efficient implementation. The filter removes noise while preserving sharp edges in the signals. The circuit can operate up to 80 MHz clock rates and it is capable of filtering real time video signals including future HDTV applications. The window size is adjustable from 3 to 257 samples.© (1988) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.Keywords
