摘要/Abstract

摘要： SAR图像数据量大,常规识别算法复杂、处理耗时,难以满足实时性要求。针对这一问题,提出一种基于OpenMP多核计算的SAR图像目标分类算法。在分析基于模板匹配的SAR图像目标分类算法的基础上,给出基于OpenMP多核计算技术的图像处理并行处理框架,实现SAR图像目标分类算法的并行计算。最后,采用所提方法对3类目标进行分类识别实验,SAR图像分类识别的处理速度提高了8倍,表明了该方法是有效的。

Abstract: The amount of a SAR image is very large usually,meanwhile,the ordinary recognition algorithm is complex and time-consuming.Aimed to solve this jam,a kind of target classification method of SAR image based on OpenMP is proposed.Firstly,the model-template based recognition algorithm is analyzed.Secondly,the OpenMP is applied to build the parallel calculation frame of SAR image target classification method.Finally,the tests are completed by classifying 3 kinds of objects.The test results show that the processing speed is improved by 8 times,and the proposed method is available.

Key words: SAR image,Target recognition,Parallel calculation,OpenMP
