Abstract According to the relationship between spatial distances and human psychological perception, a new weighting function is presented based on the psychological distance. Combined with the standard median filter (SMF), a kind of adaptive median filter is proposed. The experimental results show that the proposed filter, compared with the SMF and several other representative improved median filters, achieves better filtering effect on noise attenuation, and edge or detail preservation.
