This paper presents a robust parallel estimation algorithm of translation in video stabilization system. The equivalent model of translation that derived is accorded with small rotation angle comparatively. A parallel algorithm based on grey mapping is used in local motion estimation to shorten the estimation time and improve the computation efficiency. After local motion vectors are calculated  a fast filter can detect the spurious vectors avoiding possible jerks. The suggested translation estimation algorithm has been implemented on NVIDIA GTX 260  the experimental results show that  the average time of the estimation and compensation finished in 16 ms/frame  and stabilize 1k1k pixels sequence gray video up to 60 frames/s. 2010 IEEE.   Local and parallel finite element algorithms for the Navier-Stokes problem 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2006, 卷号: 24, 期号: 3, 页码: 227-238 作者:  He, YN;  Xu, JC;  Zhou, AH;  Aihui Zhou   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 Navier-Stokes problem  finite element  two-grid method  local and parallel algorithm   Local and parallel finite element algorithms based on two-grid discretizations for nonlinear problems 期刊论文  OAI收割 ADVANCES IN COMPUTATIONAL MATHEMATICS, 2001, 卷号: 14, 期号: 4, 页码: 293-327 作者:  Xu, JC;  Zhou, AH   |  收藏  |  浏览/下载：18/0  |  提交时间：2018/07/30 adaptive  finite elements  local a priori and a posteriori error  estimates  nonlinear  parallel algorithm  two-grid method   Local and parallel finite element algorithms based on two-grid discretizations 期刊论文  OAI收割 MATHEMATICS OF COMPUTATION, 2000, 卷号: 69, 期号: 231, 页码: 881-909 作者:  Xu, JC;  Zhou, AH   |  收藏  |  浏览/下载：16/0  |  提交时间：2018/07/30 adaptive  finite elements  local a priori and a posteriori error estimates  nonsymmetric  parallel algorithm  two-grid method
