（携帯電話） によるバーコードや画像などの撮影を起点とし，関連する情報を提示するサービスが提供されているが，撮影画像の識別はサーバでの処理が前提であった．本論文では，画像辞書データを端末内に格納し，撮影した静止画像の識別処理を端末内で行うことで，通信環境によらない高いレスポンスの情報提示サービスが実現できる画像識別方式を提案する．本論文の方式は，画像を矩形ブロックに分割した後，各々のブロックで 2 つに分割した領域の平均画素値の差分 （勾配） を算出し，勾配の系列を画像の特徴量として識別に用いる．特徴量に画素の絶対値を用いないため，カメラ撮影で生じる照明変動やボケなどの劣化にも影響を受けにくい．また，処理の負荷も低く，PC に比べて処理能力・メモリ容量などのリソースが限られる携帯端末でも実装可能である．本方式を市販の携帯電話に実装し，低リソース環境においても高速に動作し，高い識別性能を示すことを確認した．","subitem_description_type":"Other"}]},"item_3_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"If the user is to gain easy access to more sophisticated content-based services, mobile devices must have highly efficient image-based retrieval functions. Since current technologies were designed for the server, this paper proposes a light-weight algorithm to extract image features. The algorithm yields a compact feature by extracting only a simple pixel value inclination in each block partitioning the image; each block is quartered and the difference between the average value of pixels in the target quarter and the average value of those in the remaining quarters is taken to be the \"inclination\" value of the block. The resulting feature (the sequence of inclination values of the block) can be used to identify content by accessing compact records held in the mobile's memory and thus access the appropriate services in a time and cost-effective manner. The method is implemented on a typical modern cell-phone with camera and validated in experiments on images degraded by noise, image distortion, and lighting effects. The results show that the proposed method is superior to existing ones.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"21","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"10","bibliographicIssueDates":{"bibliographicIssueDate":"2009-03-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":60715,"updated":"2025-01-22T03:01:31.517088+00:00","links":{},"created":"2025-01-18T23:23:05.206108+00:00"}
