Generating stone-striped images by bilateral minimum and maximum filters

This short paper proposes a non-photo realistic rendering method which generates images imitating the striped patterns that appear when natural rock like Malachite or Laguna Agate is cut. The proposed method generates stone-striped images by using bilateral minimum filter and bilateral maximum filter iteratively. In order to validate the effectiveness of the proposed method, the attractiveness of the images generated from several gray-scale images by the proposed method was evaluated visually. As a result of the experiments, we showed that the images generated by the proposed method are quite similar to the striped patterns that appear when natural rock is cut.
