8 September 2011High-throughput median filter for high-performance infrared imaging system
Many high-performance infrared imaging systems have been designed in recent years. This poses real-time challenges to
existing infrared image processing methods. Median filter is a nonlinear filtering technology widely used in infrared
imaging system to smooth image and correct missing pixels. Traditional median filter implementation is time-consuming
with long sorting cycle, which cannot meet the real-time processing requirement of high-performance infrared imaging
system. In this paper we present a new architecture for median filter. The proposed architecture optimizes the
comparators with pipeline design in order to enhance the processing velocity of sorting. Experimental evaluation and
comparisons show high efficiency of our design.
