In the method, the criteria to optimize the shape deformation are the similarities of two derivative vectors at each constrainting position. The scaling factors and the rotations of the similarity at each position of curves non-uniformly result from optimizing the constraints for curve refinement. The Bezier representation is converted into the representation using only the derivative vectors that are suitablely selected for refinement. The shape refinement is achieved by optimizing these converted representation variables. The constraints for similarity of curvature or its variation are employed to keep the similarity in shape. The method is suitable for interactive curve refinement by intuitive manipulation: e.g. interfaces for shape refinement of clip arts, illustrations or sketches.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"63105","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SATOH, MAKOTO"}]},{"nameIdentifiers":[{"nameIdentifier":"63106","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MIWA, JOUJI"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人情報処理学会"}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(C) Information Processing Society of Japan"},{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。 Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
