A method of impulse noise removal using level detection <Abstract> In this paper, we propose a new impulse noise filtering procedure from images using level detection.In our method, we use directional windows allowing continuity of edge. In our system, an window that is selected from multi-windows includes flat region.Thus, selected window has low variation in pixel values, and enhances the performance of restoration at edge. Extensive simulations indicate that proposed method performs significantly better than traditional methods. |
