Abstract :
In this paper, a pixel value restoration method for images corrupted by impulse noise is proposed. For example, the median filter is a well-known solution for impulse noise removal. However, it cannot process well at line structures in images. We therefore propose an effective method in the view point of line structure restoration. The proposed method considers line structures in four angles. The key point of the method is to consider the two adjacent lines of the line which pass through the target pixel.
