dc.description.abstract | ITU-T (VCEG) and ISO/IEC (MPEG) collaborated and formed the joint collaborative team on video coding (JCT-VC) in April 2010 to develop the next-generation video coding (NGVC) standard.. HEVC standard doubles the coding efficiency and the approximately 50% less bit rate with respect to H.264/AVC, at nearly the same video quality at expense of increased complexity. In this thesis, a technique is proposed to reduce the complexity of HEVC intra coding to get better encoding time, involving two steps - first by optimizing the PU (prediction unit) size decision process using texture complexity analysis by intensity gradients and second to obtain the reduced prediction modes by applying a combination of rough mode decision (RMD) and most probable modes (MPM) thereby reducing the number of modes based on rate distortion optimization (RDO) followed by residual quad-tree (RQT) which is used to simplify the entire processThe technique developed in this thesis achieved an average gain of 47.25% encoder time when implemented for several test sequences at very less loss in performance with high complexity reduction. | en_US |
