These shape coding and spatial scalability cam be used independently. Combination of these two tools will be integrated in MPEG4 version2. In this report, we present the coding efficiency of the combination of shape coding and spatial scalability, and ideas of object based spatial scalability applications.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"18","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"13","bibliographicIssueDates":{"bibliographicIssueDate":"1999-06-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"52(1999-AVM-025)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":41580,"links":{}}
