Fast inter mode selection algorithm for H.264/AVC

A novel inter mode decision algorithm was presented.Three methods were adopted by the algorithm to improve coding efficiency.Firstly, early skip mode decision was employed.Secondly,foreground and background were separated by video segmentation algorithm,so the candidate modes can be decided.Thirdly,a fast intra mode decision algorithm was proposed.It can omit some unnecessary computation of Motion Estimation(ME) and rate distortion optimization(RDO).Thus,the new algorithm saves the encoding time without loss of image quality.
