文章对湍流退化图像的双重循环迭代图像复原算法的计算流程进行了分析,将算法的串行计算模式转换为并行模式,提出了基于并行模式的多结点并行处理方法。成功地实现算法的并行计算模式到多结点结构的有效映射,对算法的程序代码进行了有效移植,在多结点系统上运行通过。实验结果表明,不仅提出的并行校正方法有效,而且提高了图像复原处理帧频数。

The computation procedure of Turbulence - degraded image restoration algorithm based on double circulation iterations is analyzed in this paper. The serial computing mode of the restoration algorithm is converted into a parallel mode and a parallel processing method of multi- nodes based on the parallel computing mode is proposed. The parallel computing mode is mapped into multi - nodes structure successfully and the program codes are transplanted on multi - nodes system. The experiment result shows that the proposed parallel method is effective for raising the frames per second of image restoration processing.
