With the increasing adoption of cloud computing for data storage, assuring data service reliability, in terms of data correctness and availability, has been outstanding. While redundancy can be added into the data for reliability, the problem becomes challenging in the “pay-as-you-use” cloud paradigm where we always want to efficiently resolve it for both corruption detection and data repair. Prior...
In this paper, we propose two algorithms to improve the rate-distortion performance and reduce the computational complexity, respectively. Due to the observation that content does not change dramatically from frame to frame in majority of cases and the effect of aliasing stays almost constant between consecutive frames, we assume that adaptive filters for the previous frame could accurately compensate...
The technique of distributed storage coding has been widely used in wireless sensor networks for increasing the robustness of data storage and efficiency of data retrieval. Existing works mainly focus on scenarios in which each storage node stores a linear combination of a subset of K data packets generated by different source nodes. By solving the linear equations, a collector can recover all the...
This paper proposed a fast mode decision algorithm for H.264. It performs SKIP mode test firstly. If the SKIP mode is not suitable for the current MB, it performs 16times 16 mode test secondly. If the 16 times 16 mode is not suitable for the current MB, candidate modes for current MB are inferred from given coded correlated MBs by adopting the information of defined mode subsets. Then bottom-up merging...
