Median-smooth filtering and its hardware implementation

The median filtering and smooth filtering were analysed, and on this basis, a combined method, the median-smooth filtering method, that integrates both their strong points was put forward here. The new method improves the quality of image sequence, and its hardware implementations were also presented in this paper. This filtering method has already been used in the target image processing system and can be used for image tracking system in the actual combat if equipped with the signal processing chip of fast speed.
