Remote sensing image segmentation on quaternary strata based on mathematical morphology method

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.
