Generation of islamic-pattern-like images by quadtree segmentation and weight-shifted color bilateral filter

The non-photorealistic rendering method for generating islamic-pattern-like images from input color images by using weight-shifted color bilateral filter has been proposed. However, islamic pattern generated by the conventional method was constant in the size and interval. Therefor, we propose a method for generating islamic-pattern-like images that partially change the size and interval of islamic pattern by using quadtree segmentation. To validate the effectiveness of the proposed method, we conduct comparative experiments with the conventional method by using a questionnaire survey. As a result of the experiments, we showed that the proposed method can generate islamic-pattern-like images that looks impressive and beautiful than the conventional method.
