Abstract -
Digital Topology deals with properties and features of 2-dimensional and 3- dimensional digital images that provide a sound mathematical basis for image analysis and image processing. Rough set theory is a powerful tool for dealing with uncertainity, granulity and incompleteness of knowledge in information system. This paper describes the relation between rough sets and regularity to digital topology using the upper and lower approximation operators .Filters are applied in digital processing for computer vision and computer graphics. The connection between 8- Quasi-Discrete topology and root images of the 2-D cross-median filter in digital pictures which are left unchanged when the cross median filter is applied are established.
