Experiments showed that input illustrations are improved by our method. Although computational models that apply beautification rules to simple primitives have been extensively studied, defining models that apply these rules to freeform shapes remains a challenge. In this study, we use constrained Delaunay triangulation to detect spatially and geometrically related local parts. Then, we combine a novel set of design principles of organic geometries ―parallelism, smoothness, shape similarity, and co-circularity―as beautification rules with feature-preserving smoothing, which were independently applied in previous studies. Our method involves three steps: geometry evaluation, diffusion filtering, and fitting. The first step involves the evaluation of geometric properties based on the design principles for constrained Delaunay edges. The evaluation results are then smoothed while preserving their features. Finally, the fitting step finalizes those shapes that are best balanced by minimizing geometric energies among the different design principles. Results from viewer surveys indicate that our method beautifies images adequately compared to the previous method.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1338","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1329","bibliographicIssueDates":{"bibliographicIssueDate":"2015-05-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"56"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T19:07:49.327082+00:00","created":"2025-01-19T00:19:34.363729+00:00","links":{},"id":142074}
