摘要：This paper presents an outline for removing noise in digital images. We see that the real time images are get more corrupted while acquisition, processing and transmission. As we deal 98% of our daily work on real time application data. So to suppress noise and elimination of noise from real time images is a research area for the developers, that how to predict noise and to remove that one noise from the image. As the real time images deals with spatial domain area. So in this paper we present a non-liner filter that may used to detect and remove the noise from digital images. The proposed filter is implemented in MatLab. There are so many filters available in literature, some are used to remove substitutive noise and some for additive noise but no filter is used to reduce noise from real time images. So we give a spatial filter for digital image de-noising used for real time applications.
