The finalized international standard for multiview video coding (MVC) is an extension of H.264. In the joint model of MVC, variable size motion estimation (ME) and disparity estimation (DE) are introduced to achieve the highest coding efficiency with the cost of very high computational complexity. A low complexity mode decision algorithm is proposed to reduce complexity of ME and DE. An experimental...
The high computational complexity of multi-view video codecs makes it necessary to speed up for their realization in consumer electronics. Since fast encoding algorithms are expected to adapt to different video sequences, this paper proposes a fast algorithm that consists of fast mode decision and fast disparity estimation for multi-view video coding. The fast mode decision algorithm applies to both...
In this paper, we propose an adaptive early termination algorithm for motion estimation in multi-view video coding (MVC). Currently, in order to find the optimal motion vector (MV) during MVC, all the reference frames need to be traversed, but the time consumption would be huge for a 7-modal block during the whole coding process. In the hope of reducing the coding time-consumption and meanwhile maintaining...
Multiview video coding (MVC) is essential to many 3D video applications. Because MVC inherently contain more visual data and may employ inter-view prediction additional to temporal prediction the involved computational complexity is much higher than conventional single-view encoders. Fast algorithms are thus very desirable for the practical use of MVC. In this paper, we use coded block patterns, mode...
In order to achieve a better coding performance in Multi- view video coding (MVC), the search range for both motion estimation (ME) and disparity estimation (DE) are set twice as large as necessary for ME alone, which brings great computational complexity to the encoder. Based on the behavior analysis of disparity estimation, a simple yet effective fast search algorithm, inter-view search range prediction...
