To reduce the transmission bitrate, virtual view synthesis is an important technique for three-dimensional television (3DTV) and free viewpoint television (FTV) applications. The main aim of virtual view is to synthesize the virtual view sequence of some viewpoint from multi-view video plus depth sequences taken by parallel or non-parallel cameras. In this study, the proposed virtual view synthesis...
In this study, a new video super-resolution (SR) reconstruction approach using a mobile search strategy and adaptive patch size is proposed. Based on the nonlocal-means (NLM) SR algorithm, the mobile strategy for search center and adaptive patch size are proposed to reduce the computational complexity and improve the visual quality, respectively. Based on the experimental results obtained in this...
In this study, a computation-aware scheme for motion estimation (ME) in H.264 is proposed. The objective of the proposed scheme is to distribute the available ME computation power of H.264 video encoding to get better coding efficiency. In this study, the temporal motion vector prediction technique is used to get the predicted motion vectors (PMVs) of macroblocks. The sum of absolute components of...
In this study, a computation-aware scheme for motion estimation (ME) in MPEG-4 is proposed. The objective of the proposed scheme is to properly distribute the available ME computations of the MPEG-4 encoder. Here, the temporal motion vector prediction technique is used to get the predicted motion vector (PMV) of each macroblock (MB). The sum of absolute components of the PMVs of all the MBs in a video...
In this study, a new fast full search (FFS) motion estimation (ME) algorithm for H. 264/AVC is proposed. First, a modified data reusing (MDR) technique is proposed to speed up the average processing time by reducing sum of absolute difference (SAD) computations. In the proposed MDR technique, both unnecessary and repeated ME computations will be reduced. Second, the revisited search order (RSO) technique...
