paper proposes a data-embedded-reduction-image generation method which utilizes for high-quality image enlargement. Generally, image enlargement is defined as a method to generate a high-resolution image from one or plural low-resolution images. On the other hand, in this paper, we assume that a high-resolution image is available for the processing. The proposed method embeds pixel's information, which is lost in the reduction process, into the reduction-image. In the image enlargement process, the proposed method reads the embedded information then utilizes it to generate a high-resolution image. An effectiveness of proposed method is verified by some experiments. The results show that the proposed method achieves better performance than conventional methods when it uses 2 bits embedded data for each generated pixel.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-09-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2012-AVM-78"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
