摘要：Gray System Theory (GST) is employed to solve problems with less data, little sample, and insufficient experience, it has been successfully applied to medicine, industry technology, and so on. In this paper, a Gray Model (GM) based intra prediction method for H.264/AVC is proposed. For a certain block, when all the predicted values (obtained from the existing intra prediction methods) are similar, they are sent to a Gray system so as to obtain the final prediction results. Accordingly, the rate distortion decision procedure could be saved; meanwhile the mode information could also be saved. Since the encoder and decoder can determine whether different prediction results are similar or not, no additional flag information should be included into the bit-stream. Experimental results demonstrate that by integrating the GM-based prediction method into the H.264/AVC Joint Model version 15.1 (JM15.1), an average 2.994 % bit rate and 39.28 % coding time can be saved while maintaining the same quality of reconstructed videos. © Springer-Verlag Berlin Heidelberg 2014.
