Impulse Noise Removal of Digital Image Considering Local Line Structure
Shi Bao, Go Tanaka · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2019
For the impulse noise removal from a digital image, most of existing methods cannot repair line structures in an input image. In this letter, a method which considers the local line structure is proposed. In order to judge the direction of the line structure, adjacent lines are considered. The effectiveness of the proposed filter is shown by experiments.
