Error Resilient Coding Based on Reversible Data Embedding Technique for H.264/AVC Video
In this paper, a prescription-based error concealment (PEC) method is proposed. PEC relies on pre-analyses of the concealment error image (CEI) for I-frames and the optimal error ...

Runtime compilation techniques for data partitioning and communication schedule reuse
In this paper, we describe two new ideas by which HPF compiler can deal with irregular computations e ectively. The rst mechanism invokes a user speci ed mapping procedure via a s...

Location-based Spatial Queries with Data Sharing in Wireless Broadcast Environments
Location-based spatial queries (LBSQs) refer to spatial queries whose answers rely on the location of the inquirer. Efficient processing of LBSQs is of critical importance with th...
