In this paper, we present a model-based video coding method that uses input from colour and depth cameras, such as the Microsoft Kinect. The model-based approach uses a 3D representation of the scene, enabling several other applications besides video playback. Some of these applications are stereoscopic viewing, object insertion for augmented reality and free viewpoint viewing. The video encoding...
This paper presents an efficient method in deciding macro-block mode and selecting prediction mode for intra prediction in H.264/AVC high profile. H.264/AVC supports nine intra prediction modes for luminance 4x4 and 8x8 blocks. The predictors include 8 directional modes and intra DC mode, which is non-directional mode. For luminance 16x16 blocks, the following 4 intra prediction modes are used: Vertical,...
This paper presents a fast intra mode decision algorithm using the sum of absolute transformed differences (SATD) in order to reduce the encoding time. Our algorithm consists of two main techniques: Early block-mode decision and candidate directional-mode selection. First, we use the early block-mode decision method, I4MB skip, to avoid unnecessary computation for I4MB. If all the 16 4x4sub-blocks...
Many fast block-matching algorithms (BMAs) reduce computational complexity by screening the number of checking points. Although many fast BMAs reduce computations, sometimes they should endure matching errors in comparison with full-search algorithm (FSA). In this paper, a novel fast BMA for constrained one-bit transform (C1BT)-based motion estimation is proposed in order to decrease the calculations...
