IEEE International Symposium on Circuits and Systems (ISCAS)
作者: Sven Klomp Marco Munderloh Yuri Vatis Jorn Ostermann Institut für Informationsverarbeitung Leibniz Universtät Hannover Hanover Germany
In video coding standards like H.264 / MPEG-4 AVC, the encoder performs motion estimation in order to utilise temporal dependencies within a sequence. In addition to the rate of the residue, the encoder has to allocat... 详细信息
