Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Lower Bounds and Accelerated Algorithms in Distributed Stochastic Optimization with Communication Compression
通信压缩 分布式 随机优化 下界 加速算法
2023/11/29
Communication compression is an essential strategy for alleviating communication overhead by reducing the volume of information exchanged between computing nodes in large-scale distributed stochastic ...
Smooth compression, Gallager bound and Nonlinear sparse-graph codes
Data compression data smoothness coding
2015/8/21
A data compression scheme is defined to be smooth if its image (the codeword) depends gracefully on the source (the data). Smoothness is a desirable property in many practical contexts, and widely use...

Compression-Induced Rendering Distortion Analysis for Texture/Depth Rate Allocation in 3D Video Compression
Compression-Induced Rendering Distortion Analysis Texture/Depth Rate Allocation 3D Video Compression
2010/12/20
In 3D video applications, the virtual view is generally rendered by the compressed
texture and depth. The texture and depth compression with different bit-rate overheads can lead to different virtual...
B-picture coding in AVS video compression standard
B-picture coding AVS video compression standard
2010/12/17
This paper first gives a brief overview of the Chinese audio–video coding standard (AVS1) especially on prediction modes of motion compensation for B-picture. Furthermore, two techniques adopted by AV...
Context-based Arithmetic Coding Reexamined for DCT Video Compression
Context-based Arithmetic Coding DCT Video Compression
2010/12/17
This paper presents a new context modeling technique for arithmetic coding of DCT coefficients in video compression. A key feature of the new technique is the inclusion of all previously coded coeffic...
A Novel Coefficient Scanning Scheme For Directional Spatial Prediction-Based Image Compression
Coefficient Scanning Scheme Prediction-Based Image Compression
2010/12/14
Spatial prediction is a promising technique for image coding. For example, the coming AVC/H.264 standard adopts directional spatial prediction in the Intra frame coding. Similar to the traditional DCT...
