Typical solutions regard each word as a point and solve the retrieval as points-to-points matching. Locally Likely Arrangement Hashing (LLAH) uses affine/perspective invariants as feature and achieves real-time retrieval system based on hashing. LLAH contains a redundancy to solve the permutation ambiguity of points detected from an image. In this paper, we propose to introduce P2-invariant, perspective and permutation invariant, as feature for document image retrieval. Contrast to the existing methods, the proposed method solves the retrieval problem by 5-tuple-to-5-tuple matching technique. The experimental result shows the performance of the proposed method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-08-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2016-CVIM-203"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":174412,"updated":"2025-01-20T06:41:30.939312+00:00","links":{},"created":"2025-01-19T00:44:36.939983+00:00"}
