In this paper, the one-dimensional grey polynomial interpolation (GPI) presented in [10] is applied to impulse noise removal. The proposed approach is motivated by the following observations. First, a median based noise removal approach can be considered as a variation of neighborhood interpolation which is based on the zero-order polynomial. Second, it is(More)
In this paper, a noise replacement scheme based on adaptive polynomial interpolation (NRAPI) is proposed, where the perfect noise detection is assumed. In the NRAPI, the zero-order and the first-order polynomial interpolation schemes are adaptively applied in the noise replacement according to the noise density. It is observed that the proposed zero-order(More)
