It is a developing project to monitor ocean oil spills by satellite remote sensing, and the image processing is the key work of it. The research of image processing of oil spills is limited in the world and no scientific method has been formed. This paper that is based on the experiment of surveying ocean oil spills, begins with analyzing the contrast between different thickness, different kinds of oil slick and clean seawater, making use of the data from Landsat and NOAA to take a lot of tests of identification of target information by all of digital image processing methods and gets some simple and utility ways in oil spills image processing.
