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.
