We have proposed a sign language recognition method based on the Hidden Markov Model tracking the signer's arm motion. However, the method used only arm motion and it was unable to distinguish the words with the different hand shape and the same arm motion. In this study, the hand shape images were extracted when the arm motion stopped or the movement direction of arm changes significantly. The extracted images are classified by the Support Vector Machine and identified as the proper sign word. As the result of the recognition experiment, the recognition accuracy was about 80% for the words with the different hand shape.","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":"2014-01-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"45","bibliographicVolumeNumber":"2014-CVIM-190"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":98012,"updated":"2025-01-21T12:40:51.825190+00:00","links":{},"created":"2025-01-18T23:44:20.682828+00:00"}
