The skip decision is based on a partially computed Sum of Absolute Differences metric combined with utilization of the Lagrangian Rate- Distortion cost function from the previous frame. A statistical analysis of the spatio-temporal characteristics of the Rate Distortion cost function and SAD metric for skip decisions is provided. Experimental results show that the new algorithm outperforms existing ones in performance providing a 55% reduction in total computational complexity, a slight reduction in bit rate and negligible impact on visual quality.||Funding Details:||University College Dublin||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2006 IEEE||Keywords:||Skip prediction algorithms; Mode decision; Sum of absolute differences (SAD)||DOI:||10.1109/ICDT.2006.70||Language:||en||Status of Item:||Peer reviewed||Conference Details:||International Conference on Digital Communications (ICDT), Cap Esterel, France, 29 - 31 August, 2006|
