The tamper-proof of webpage is of great importance. Some watermarking schemes have been reported to solve this problem. For a webpage, we create the watermark according to the webpage tags by using SVD, and...
A role based hierarchical group awareness model (RHGAM) on the basis of the previous research was presented in this paper. Regarding role as the basis of the group cooperation, firstly RHGAM constructed a group cooperation environment (GCE), and then GCE was extended by group awareness content, awareness hierarchy, the task decomposition rule. The model divided the awareness information into four...
Role is an important concept in collaboration systems and CSCW systems especially in the aspect of group awareness. This paper proposes a new group awareness model based on role by the research of role in collaboration systems and the analysis of existing awareness models. In the new proposed model, the task is decomposed into activities in order to acquire the activity graph. Then the roles are extracted...
Emerging video-mining applications such as image and video retrieval and indexing will require real-time processing capabilities. A many-core architecture with 64 small, in-order, general-purpose cores as the accelerator can help meet the necessary performance goals and requirements. The key video-mining modules can achieve parallel speedups of 19times to 62times from 64 cores and get an extra 2.3times...
