Abstract：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.
