A Novel Fast Multiple Reference Frames Selection Method for H.264/AVC
Found in: Computer and Information Technology, International Conference on
By Kan Chang, Aidong Men, Wenhao Zhang
Issue Date:October 2009
pp. 156-160
Multiple reference frames motion estimation is one of the new features introduced in H.264/AVC. Although this new feature improves video coding performance, it is extremely computational intensive. Full search scheme is adopted in reference software JM, an...
Novel Fast Mode Decision Algorithm for P-Slices in H.264/AVC
Found in: Information Assurance and Security, International Symposium on
By Kan Chang, Bo Yang, Wenhao Zhang
Issue Date:August 2009
pp. 189-193
H.264/AVC encoder complexity is remarkable mainly due to variable block size motion estimation (ME) and exhaustive Rate Distortion Optimization (RDO). This makes real-time video coding very difficult. In this paper, a novel fast mode decision algorithm for...
A Novel Fast Mode Decision Scheme for Spatial Scalable Video Coding
Found in: Multimedia and Ubiquitous Engineering, International Conference on
By Wenhao Zhang, Bo Yang, Kan Chang
Issue Date:June 2009
pp. 22-25
In the scalable video coding extension of H.264 standard, the concept of inter-layer prediction is adopted to reduce the redundancy between the base layers and the enhancement layers. Thus, additional coding modes should be calculated during the macroblock...
Adaptive Intra-frame Rate Control for H.264/AVC
Found in: Multimedia and Ubiquitous Engineering, International Conference on
By Kan Chang, Aidong Men, Wenhao Zhang
Issue Date:June 2009
pp. 54-58
In this paper, we present an adaptive Intra-Frame rate-quantization (R-Q) model for H.264/AVC. The R-Q model, which is a generic relationship among the quantization value, data bits and the frame complexity, provides a mechanism to properly select the quan...
Design Methods of Multi-DSP Parallel Processing System
Found in: Computer Science and Information Engineering, World Congress on
By Wei Wu, Jun Wang, Wei Li, Wenhao Zhang
Issue Date:April 2009
pp. 458-464
In this paper, the cascaded topology of Multi-Digital Signal Processor (DSP) parallel processing system is presented, and the common architecture for multi-DSP parallel systems is summarized. In addition, according to the features of Field Programmable Gat...
Adaptive optimizing filter for inter-layer intra prediction in SVC
Found in: Proceedings of the seventeen ACM international conference on Multimedia (MM '09)
By Aidong Men, Kan Chang, Wenhao Zhang
Issue Date:October 2009
pp. 865-868
Several inter-layer prediction techniques are adopted in the H.264 Scalable Video Coding Extension to increase the compression efficiency. For spatial scalable intra-coded frames, the prediction of macroblock in the enhancement layer is obtained by upsampl...
