The Performance of High Efficiency Video Coding (HEVC) has been improved greatly compared with H.264/AVC including some parallel processing tools to achieve fast implementation on multi-core or many-core platforms. However, CU-level parallel processing is still a challenging issue. In this paper, the relation among spatial motion candidates is analysed firstly. Then, a parallelism spatial candidate...
An improved method for the TZSearch fast motion estimation algorithm in the Joint Multi-view Video Coding (JMVC) is proposed in this work. It is based on early terminating the calculation of Sum of Absolute Difference (SAD) and increasing the number of predicted motion vectors to reduce the inter-view redundancy and save the encoding time. Experimental results show that the proposed method has much...
In this paper., we propose an efficient temporal DIRECT mode decision algorithm for H.264/AVC inter bi-predictive (B) frame video coding to improve the coding efficiency. In the suggested technique, in addition to the motion vector (MV) of the co-located block we also employ MVs of eight neighboring blocks for DIRECT mode decision. The best MV is selected for DIRECT mode decision based upon the sum...
In accordance with the complexity of AVS motion search and block mode selection algorithm, the paper poses a AVS quick mode selection algorithm based on premature termination norm and adaptive threshold. The algorithm can avoid much cost calculation of the useless macro block and save a lot of time on moving search and block mode selection in encoding process. Experimental results show that the computational...
Recently, scalable video coding technique has attracted a lot of attention for its desired scalable functionality and coding efficiency. H.264/SVC encodes a video in a hierarchical way by which the coded bit stream can satisfy terminals with different capability of display and different condition of network at the same time. However, the huge computational complexity of mode decision causes difficulties...
An appropriate search region is necessary for efficient multiview video coding (MVC). In this paper, the global disparity of two views is used to decide the size of the search region adaptively in the inter-view prediction of MVC. We first propose a simple method to obtain the global disparity vector (GDV) quickly, and analyze the relationship between the real disparity vector (DV) and GDV. It is...
