Visualization Analysis of Multi-Domain Access Control Policy Integration Based on Tree-Maps and Semantic Substrates
Cross-Domain Information Exchange Visualization Analysis Tree-Maps Semantic Substrates
2013/1/28
The complexity of multi-domain access control policy integration makes it difficult to understand and manage the policy conflict information. The policy information visualization technology can expres...
CONSTANT QUALITY CONTROL OF WYNER-ZIV FRAMES IN DCT DOMAIN DISTRIBUTED VIDEO CODING
Distributed video coding Constant quality control Greedy algorithm Adaptive uniform quantizer
2013/7/24
For most DCT domain distributed video coding systems, xed uniform quan-tizers are used to quantize all Wyner-Ziv (WZ) frames. However, it leads to uctuantvideo quality because the WZ frame quality is...

ESTIMATING THE VALUE OF θ IN THE INTRA FRAME FOR ρ-DOMAIN RATE CONTROL ALGORITHMS
ρ-domain Rate Control θ Estimation
2013/7/16
The ρ-domain rate control algorithm is very simple and effective. There is only one parameter, θ, used in the model. θ reflects the relationship between the rate and the quantization step. Accur...
