The technique of cable-bell filter based on parallel programming

Xu Changlong Wang Clever Shuo Hua

With the increase of the data of remote sensing image, the computation time of the edge filtering operation in single machine environment is also increased. According to the characteristics of remote sensing data, combined with MapReduce parallel distributed computing model, this paper proposes a method of migrating this operation into Hadoop cluster environment to complete the Bayes filtering operation of massive image data. The experimental results show that the cluster operation can shorten the computation time, and the calculation time will decrease with the increase of cluster node number.
