摘要
为了改善多核平台下空间域图像增强程序的性能,充分利用多核平台的计算能力,对空间域图像增强的三种算法高斯滤波、中值滤波和拉普拉斯变换进行并行设计。利用OpenMP并行库在多核平台上实现了多核并行空间域图像处理算法。在双核平台上的实验结果表明,多核并行算法能够显著提高空间域图像增强处理的效率。多核并行计算技术是提高图像处理程序性能的有效方式。
Design the parallel algorithms of the three major spatial image enhancement algorithms: Gauss filtering, median filtering and Laplacian sharpening to improve the efficiency of spatial image enhancement program and make the full use of the computation of multi-core platform. Implement the multi-core parallel spatial image enhancement in multi-core platform. The experiment in dual-core platform indicates that the multi-core parallel algorithms can greatly improves the efficiency of the spatial image enhancement. The multi-core parallel computing is a efficient method to improve the performance of image processing program.
