Paper Abstract

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.
