A novel fuzzy clustering method based on chaos immune evolutionary algorithm (CIEFCM) is presented to solve fuzzy edge detection problems in image processing. In CIEFCM, a tiny disturbance is added to a filial generation group using a chaos variable and the disturbance amplitude is adjusted step by step, which greatly improves the colony diversity of the immune evolution algorithm (IEA). The experimental results show that the method not only can correctly detect the fuzzy edge and exiguous edge but can evidently improve the searching efficiency of fuzzy clustering algorithm based on IEA.

复杂环境下起伏地形探地雷达逆时偏移成像 Article

探地雷达偏移成像中,基于高程静校正的基准面偏移方法对起伏地表下的复杂地层成像效果较差。为了优化成像效果,本文提出了一种基于麦克斯韦方程组二阶解耦形式的逆时偏移成像(reversetime migration,RTM)算法,该算法特点在于只需计算电场,且可直接从采集面而非基准面进行波场延拓,进而实现地形逆时偏移。数值模拟比较了高程静校正偏移方法和RTM 方法在地表起伏及速度横向变化情况下的成像效果,结果证明RTM 方法成像效果更好。为了进一步验证算法效果,利用美国犹他州珊瑚粉沙丘崎岖地形下的实测数据对两种方法进行了对比分析。研究表明,逆时偏移成像方法能够极大地提高复杂环境下探地雷达深度成像精度。
