Abstract:
In this paper, we propose a light robust edge preserving smoothing filter named self-quotient referential Îµ-filter. Although many filters for edge preserving smoothing have been proposed, as it often uses local information, it is difficult to preserve edge information when the images are taken under light variation. To solve the problems, we pay attention to the feature of self-quotient filter, and combine self-quotient filter and Îµ-filter. Some experiments were done to show the effectiveness of the proposed method. Throughout the experiments, the validity of our method was verified.
