【摘要】:SAR圖像數(shù)據(jù)量大,常規(guī)識別算法復雜、處理耗時,難以滿足實時性要求。針對這一問題,提出一種基于OpenMP多核計算的SAR圖像目標分類算法。在分析基于模板匹配的SAR圖像目標分類算法的基礎上,給出基于OpenMP多核計算技術的圖像處理并行處理框架,實現(xiàn)SAR圖像目標分類算法的并行計算。最后,采用所提方法對3類目標進行分類識別實驗,SAR圖像分類識別的處理速度提高了8倍,表明了該方法是有效的。
[Abstract]:The data volume of the SAR image is large, the conventional recognition algorithm is complicated, the processing time is time-consuming, and the real-time requirement is difficult to meet. In order to solve this problem, a SAR image target classification algorithm based on OpenMP multi-core calculation is proposed. On the basis of analyzing the target classification algorithm of SAR image based on template matching, this paper gives an image processing parallel processing framework based on OpenMP multi-core computing technology, and realizes the parallel computation of the SAR image target classification algorithm. Finally, using the proposed method to classify the three-class object, the processing speed of the SAR image classification recognition is improved by 8 times, which shows that the method is effective.
