employs variable block size motion compensation which supports 7 block sizes from 16x16 to 4x4. This feature enhances coding efficiency of H.264. However it increases both the computation load for motion estimation (ME) and the hardware complexity implementation. In this paper, we propose an ME algorithm using fast search method for variable block sizes and 1D-DS for H.264 video coding. Fast search method for variable block sizes consists of two search methods for the larger size block and smaller size block. The 1D-DS performs ME on large search range with low computational complexity. The experimental result shows that the proposed algorithm provides 97% reduction of workload with Image quality degradation of 0.1 dB.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"72","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告システムLSI設計技術（SLDM）"}],"bibliographicPageStart":"67","bibliographicIssueDates":{"bibliographicIssueDate":"2005-10-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"102(2005-SLDM-121)","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":27134,"updated":"2025-01-22T18:40:26.924809+00:00","links":{},"created":"2025-01-18T22:57:34.369250+00:00"}
