Abstract:	摘要： •Creates two new intra prediction modes through the concept of a finite state machine.•Adaptively selects the template shape.•Achieves 11% bit rate reduction when compared to H.264/AVC and 4% bit rate reduction when compared to HEVC. This paper presents a new approach that aims to improve the performance of the intra block coding of H.264/AVC and HEVC by using a finite state machine. Based on the high correlations between a frame’s neighboring blocks, the finite state machine is employed at both the encoder and decoder to reduce the number of bits required for intra encoding, improving the coding performance of videos. With the matching adaptive template, a better prediction block is found. Through the proposed extra intra prediction modes, the number of bits required to encode a block is reduced significantly, and thus a better intra coding performance is achieved. In addition, an early termination is proposed to speed-up the coding performance. Experimental results show that with the proposed method, the bit rate can be reduced 11% on average when compared to H.264/AVC and 4% on average when compared to HEVC. 出版者： Elsevier Inc 出版日期： 2015-05-01 出處： Journal of visual communication and image representation, 2015-05, Vol.29, p.33-45 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2015 Elsevier Inc. 識別號： ISSN: 1047-3203 識別號： EISSN: 1095-9076 識別號： DOI: 10.1016/j.jvcir.2015.01.010
