The reduction of gaussian noise is still an important task in video systems. The presented scheme consists mainly of a subband based recursive temporal filter adapted to special properties of the human visual system. This filter is supported by a spatial filter with low hardware expense, which consists of an image analysing highpass filter bank and an adaptive lowpass FIR-filter for noise reduction.
