A fast Mode Decision algorithm, based on a Pareto optimal MacroBlock classification scheme, is combined with a Dynamic Complexity Control algorithm that adjusts the MB Class decisions such that a constant frame rate is achieved. The average coding efficiency of the proposed algorithm was found to be similar to that of conventional encoding operating at half the frame rate. The proposed algorithm was found to provide lower average bit rate and distortion than Static Complexity Scaling.||Funding Details:||University College Dublin||Type of material:||Journal Article||Publisher:||Association for Computing Machinery (ACM)||Copyright (published version):||2010 ACM||Keywords:||Algorithms; H/264/AVC; Rate distortion; Real time; Mode decision; Fast mode decision; Complexity; Complexity control||DOI:||10.1145/1671954.1671959||Language:||en||Status of Item:||Peer reviewed|
