In the present paper we propose a new digital video watermarking scheme based on Principal Component Analysis. We detect the video shots based on informational content, and color similarities; we extract the key frames of each shot and each keyframe is composed of three color channels, and our proposed algorithm allows us to embed a watermark in the three color channels RGB of an input video file. The preliminary results show a high robustness against most common video attacks, especially frame dropping, cropping and recalling for a good perceptual quality.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/7087"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0389-102X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN0025048X"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8\u7d00\u8981"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "2008-05", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "69", "bibliographicPageEnd": "69", "bibliographicPageStart": "65"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "No69p65.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004041/files/No69p65.pdf"}, "version_id": "227a14fd-c4ba-4b8e-941a-688ec98b14a9"}]}, "item_title": "Multi-color channel video watermarking", "item_type_id": "15", "owner": "1", "path": ["1642837880629", "1642838406845"], "permalink_uri": "http://hdl.handle.net/20.500.12000/7087", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2008-09-02"}, "publish_date": "2008-09-02", "publish_status": "0", "recid": "2004041", "relation": {}, "relation_version_is_last": true, "title": ["Multi-color channel video watermarking"], "weko_shared_id": -1}
