AvsX开源项目现已启动, 我已在SourceForge建立了AvsX的项目网址 http://avsx.sourceforge.net. 将来有可能迁移到正式的AvsX网址: http://www.avsx.org (建设中).
AvsX decoder部分的源代码加入了该网址 http://sourceforge.net/projects/avsx/,下一步的计划,继续将AvsX encoder部分的源代码逐步加入.
由于一个人的力量有限,对AvsX的编解码器的优化难以完善,希望有更多对AVS开源编解码器有兴趣的朋友能够加入该项目. 如果想参与到这个项目或者修改源代码的，你可以把你的代码e[......]

The 89th MPEG / 31st JVT / 38th ITU-VCEG meetings are hosted by the Centre for Digital Music, School of Electronic Engineering and Computer Science of Queen Mary University of London, UK.
在前面的文章中，曾介绍过Xcode IDE环境下的CUDA设置。之前提过我的CUDA Plugin for Xcode一直设置不成功，经过一番折腾，总算是把Xcode IDE的CUDA配置给搞定了。下面介绍一下如何设置CUDA Plugin for Xcode IDE。
4. Rate-Distortion Optimized Quantization
Previously, adaptive rounding was proposed to improve quantization, which captures the statistics of the incoming residual signal and adjusts the rounding offsets accordingly. However, the adaptive rounding quantization is still based on the criterion which [......]
3. Adaptive Rounding Encoding Technique using an Equal Expected-Value Rule
As discussed above, if the input p.d.f. is Laplacian distributed and if we can estimate λ, then the optimal f can be found analytically. But, usually the estimate of input p.d.f. is not available, then, how to select the roun[......]
2. Principle of H.264/AVC Normal Quantization Scheme
2.1. Scalar dead-zone quantization
In this section the principle of H.264/AVC normal quantization scheme is described in a generalized form.
A scalar quantizer for input signal W can be decomposed into a function Z=C[W] called a classification rul[......]
1. Overview
Currently most image and video coding systems and standards such as MPEG-1/2 and H264/AVC use transform-based techniques followed by quantization and entropy coding for performing compression. The key idea is that transforms de-correlate the signal and compact the energy of a block into [......]
With recent advances in capture and display technologies, 3D video communication and entertainment services are expected to become reality and redefine the communication and entertainment services with high immersion. To enable these exciting new services, Joint Video Team (JVT) of ITU-T and MPEG ha[......]
