摘要
利用数学形态学的方法对遥感影像的第四系地层进行了影像分割实验。经实验结果得出,利用数学形态学的基本运算组合成的各种算子:高、低帽变换、滤波与阈值截取相结合的增强方法,通过选择合适的结构元素,对图像进行预处理后,就可以用形态学方法对第四系地层进行影像分割。经过处理的遥感影像,能够更有效地提取影像的目标。实验结果表明了本文所提的方法的有效性。最后,对形态学方法的不足之处和将来的研究方向展开了讨论。
In this paper experiments of image segmentation on Quaternary strata are made on RS image by morphologic methods.Based on the combination of all kinds of basic morphologic operators which leads to different top and bottom hat transformations,filtering and threshold enhancement are used to pre-process the image,by choosing appropriate structure elements,Quaternary strata can be segmented by morphologic methods.So the target of image can be extracted easier by the preprocessing approach proposed in this paper.The experimental results show that the effect of the method is satisfactory.Finally the disadvantages and future research directions of mathematical morphology method are discussed.
