基于 MPI ＋OpenMP 的红外弱小目标检测并行计算
Parallel Computing of Infrared Small Target Detection Based on MPI and OpenMP
摘要
Abstract
To get effective surveillance of the whole movement of infrared small target , multiband simultaneous detection is neces-sary.But, multiband simultaneous detection leads to substantial growth in computing time , that cannot meet the requirement of real-time target detection in practical application .To solve this problem , this paper presents a parallel hierarchical approach based on MPI and OpenMP , which makes full use of the advantages of both message-passing model and shared storage model .It is based on multi-processor node cluster for testing .Experimental results show that , this parallel version of the program can a-chieve a speedup of 8.61 compared to the serial version in the condition of same detection probability .It improves the efficiency of target detection greatly .关键词
