HEVC (High Efficiency Video Coding) is the next-generation video coding standard, which introduced many new technologies such as tree structure coding unit and a variety of intra prediction mode. Compared with H.264/AVC, HEVC has achieved higher coding efficiency but requires a very high computational complexity. So this paper proposes a fast algorithm through early termination of the CU (Codin...

A novel Wyner-Ziv scalable (WZS) video coding approach is proposed to enhance MPEG-4 fine granularity scalability (FGS). Starting from the same base layer as MPEG-4 FGS, the proposed coder can achieve higher coding efficiency using Wyner-Ziv coding, by selectively exploiting the high quality reconstruction of the previous frame in the enhancement layer bitplane coding of the current frame. This...

The promising video coding standard, H.264/AVC [1], is developed by the Join Video Team of ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG). By utilizing several new techniques, such as advanced intra predictions, variable block size ME, integer transformation, in-loop deblocking filter, H.264/AVC has achieved significant compression gain compared with pre...

An adaptive motion-compensated video coding scheme, that is based on structural video component segmentation and coding complexity analysis, is proposed in this paper. The bits are allocated more efficiently among different frame types and variant video components. A novel scene cut detection algorithm is proposed for partitioning the input video sequences into a set of shots and each shot may ...

Due to the multi-view video coding scheme using inter-view prediction stucture, increased coding complexity, and reduced multi-view video random access performance, so one proposed multi-view video coding prediction scheme is proposed on the basis of analysis and study of several typical multi-view video coding schemes in this paper. This coding prediction scheme calculates the location of base...

In this paper we present a number of advanced concepts with respect to the transformation of residual blocks in video coders, which go beyond what is incorporated in today’s video coding standards. Some of these concepts will undoubtedly be adopted as part of future standards. We discuss directional transforms for extrapolation-based prediction schemes, shape-adaptive transformation for object-...

The ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) formed, in December 2001, the Joint Video Team (JVT) with the purpose to develop a new video coding standard that it is usually known as H.264/AVC, H.264 for ITU-T and Advanced Video Coding (AVC) for MPEG. The main objective was to achieve at least the double of the coding compression, for the same v...

As a successor to the H.264/Advance Video Coding (AVC), High Efficiency Video Coding (HEVC) is invented to get more compression and high quality video. But HEVC increases the complexity of video coding. To reduce this complexity various methods are proposed with different approach which also enhance the video compression and quality of video. This paper contains different techniques for video t...

Video coding standards are primarily designed for efficient lossy compression, but it is also desirable to support efficient lossless compression within video coding standards using small modifications to the lossy coding architecture. A simple approach is to skip transform and quantization, and simply entropy code the prediction residual. However, this approach is inefficient at compression. A...

In this paper, an improved low complexity algorithm for 3D-HEVC is proposed to reduce the computational complexity. The basic idea of the method is to utilize the boundary homogeneity of texture and depth map which is generated by Laplacian filter. Firstly, based on the evaluation result of the boundary homogeneity, an early coding unit (CU) decision method is proposed to achieve the low comput...
