Abstract
Oil spills are almost constantly present in recent years, which cause ecological disaster of marine environment. It is important to detect the area of oil spill to take rescue measurement in time. The paper took the EnviSat Asar image as example to detect the boundary of oil spills. Firstly, the paper removed speckle noise by Histogram Equalization. Then, image segmentation was carried out by open-close mixed operation in mathematical morphology. At last, the region of oil spill was exacted independently.
