数学形态学在地震相干属性提取中的应用
|
摘要
形态学运算的目的在于抽取图像的相关结构,这些结构可通过其子图表示为集合,可利用称之为结构元素的已知形状的另一集合对图像进行探测。形态学的基本运算如膨胀、腐蚀、开、闭等都需要结构元素的参与才能实现。文中通过对比形态学处理前、后地震资料的相干结果可知,形态学的滤波作用可以使断层与河道的表现更加明显,同时还可以清晰表现地质异常体中的断层,因此利用形态学滤波器处理地震资料可以提高相干效果。
The purpose of the morphology operation lies in extraction of the related structures of the image,through their sub-graphs those structures can be expressed as a set,the image can be detected by utilizing of the other set which is called structure element and its shape is already known.The involvement of the structure is needed in the basic calculations of morphology,such as expansion,corrosion,open-close operation and so on.By comparing coherent results from pre-morphology processing and post-morphology processing,the filtering function of the morphology could make faults and channel more visible,at the same time the faults can be clearly identified in geological anomalous body,as the result application of filtering function of the morphology in seismic data processing could raise coherence effects.
