- W251018943 abstract "AbstractThe depth map extraction from stereo video is a key technology of stereoscopic 3D video as well as view synthesis and 2D-3D video conversions. Sum of Absolute Differences (SAD) is a representative method to reconstruct disparity map. However, dense disparity map implementation requires heavy computations and extensive memory accesses. In this situation, the rapid advance of computer hardware and popularity of multimedia applications enable multi-core processors to become a dominant market trend in desk-top PCs as well as high end mobile devices; this movement allows many parallel programming technologies to be realized in users computing devices. Therefore, this paper proposes a parallel algorithm for SAD operation using a shared memory programming, OpenMP, which can provide the advantage to simplify managing and synchronization of program threads. The parallel implementation results show the 2.5 times of performance improvements on the processing speed compared with the serial implementation.KeywordsShared MemoryOpenMPExtensive Memory AccessSerial ImplementationStereo VideoThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves." @default.
