paper describes a real-time human tracking method using ellipsoid model.Several images that simulate real image are generated by using a camera parameter and enviromental information.These images are compared with an input image and human positions are determined by those similarities.A human is simply represented by a ellipsoid to achieve a real-time operation on a standard personal computer.To integrate some tracking systems using this method can be achieved easily because human positions are measured and managed on a world coordinates.In accuracy evaluations for a standing human,the average errors were within about 0.2 meter except the case that both head and foot were occluded.In the tracking experiment for 2 humans,the algorithm was able to work successfully.However,tracking sometimes failed because of shadows or reflections.We will consider the integration of several systems.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4096","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"4087","bibliographicIssueDates":{"bibliographicIssueDate":"1999-11-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"11","bibliographicVolumeNumber":"40"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"メディア情報処理"}]},"weko_creator_id":"1"}}
