| Abstract(in English) | Estimation of a suitable window shape and appropriate weights in weighted median filters is one of important problems. In this study, we formulate the design of weighted median filter as an optimization problem, and optimal window shapes and weights are estimated directly from degraded images. In the previous work, we estimated them by using a Genetic Algorithm (GA) on texture images corrupted by positive impulse noises. Here, we extends our proposed unsupervised design to the positive and negative impulse removal. Through experiments, it is shown that designed filters outperform compared to conventional impulse noise filters from the perspective of both high noise removal performance and preservative quality. |
