Intelligent video surveillance in modern city is becoming more and more popular, and higher quality of images is required in video automatic analysis and recognition. In this paper, we develop a kind of haze-free method for outdoor foggy video image with low contrast. The method is based on the multi-scale guided filtering combined with Retinex algorithm. Compared with the traditional series method...
In this paper we put forward EXrML, which extend the current use rule description tool XrML to solve the problem brought by the digital content nested protection. EXrML has the feature of supporting describing multiple use rules' same type element comparability. Based on the EXrML we conclude that the root of multiple use rules conflict lies in three elements conflict: principal, right and condition...
Scalability and efficiency are important for designing application-layer multicast protocol. In this paper, a short delay degree-constrained hierarchical protocol-SDDM is proposed for application-layer multicast. It adopts the idea of layer and cluster to construct multicast group members into a hierarchical architecture. When constructing the hierarchical architecture, the end host heterogeneity...
