The discrete wavelet transform (DWT) has been widely used in scalable video coding for its advantages in multi-resolution analysis and subband decomposition. In this paper, a spatially scalable video coding system based on H.264 coding method and in-band overcomplete discrete wavelet transform (ODWT) technique is proposed, which integrates the good compression performance of H.264 in low freque...

In the new video coding standard, MPEG-4 AVC/JVT/H.264, motion estimation is allowed to use multiple reference frames. The reference software adopts full search scheme, and the increased computation is in proportion to the number of searched reference frames. However, the reduction of prediction residues is highly dependent on the nature of sequences, not on the number of searched frames. In th...

Byung-Gyu Kim et al. 425 We propose a fast macroblock mode prediction and decision algorithm based on contextual information for Pslices in the H.264/AVC video standard, in which the mode prediction part is composed of intra and inter modes. There are nine 4×4 and four 16×16 modes in the intra mode prediction, and seven block types exist for the best coding gain based on rate-distortion optimiz...

This paper seeks to provide a selective intra-prediction and optimized inter-prediction methods in H.264/AVC standard. In order to reduce the temporal and spatial redundancy more effectively, motion compensation uses variable block sizes, while directional intra-prediction investigates all available coding modes to decide the best one. When the rate–distortion (R–D) optimization technique is us...

Exploiting spatial redundancy in images is responsible for a large gain the performance of image and video compression. The main tool to achieve this called intra-frame prediction. In most state-of-the-art coders, intra prediction applied block-wise fashion. Up now angular was dominant, providing low-complexity method covering variety content. With deep learning, however, it possible create met...

With multi-layer encoding and Inter-layer prediction, Spatial Scalable High Efficiency Video Coding (SSHVC) has extremely high coding complexity. It is very crucial to speed up its promote widespread cost-effective SSHVC applications. Specifically, we first reveal that the average RD cost of Reference (ILR) mode different from Intra mode, but they both follow Gaussian distribution. Based on thi...

Due to multi-layer encoding and Inter-layer prediction, Scalable High Efficiency Video Coding (SHVC) has extremely high coding complexity. It is very crucial improve its speed so as promote widespread cost-effective SHVC applications. In this paper, we propose a new probability-based fast Intra prediction algorithm for spatial SHVC. More specifically, first, integrate depth probabilities with t...
