摘要： Although H.264/AVC is a promising video coding standard that achieves excellent coding performance in terms of visual quality and bitrate, its extremely high encoding complexity raises concerns about its computational burden on real-time applications. This work presents a multi-phase classification (MPC) scheme that builds a mode decision tree according to the clustering of rate-distortion costs. A nearest cluster mean criterion is used to examine candidate modes phase by phase, and a performance control mechanism is incorporated to maintain coding performance. Experimental results confirm that the proposed MPC algorithm reduces encoding time by an average of 68% with only negligible performance degradation. 其他題名： TMM 出版者： New York, NY: IEEE 出版日期： 2012-06 出處： IEEE transactions on multimedia, 2012-06, Vol.14 (3), p.693-702 資源來源： IEEE Electronic Library (IEL) 版權： 2015 INIST-CNRS 識別號： ISSN: 1520-9210 識別號： EISSN: 1941-0077 識別號： DOI: 10.1109/TMM.2012.2186793 識別號： CODEN: ITMUF8
