摘要
国内外海上重大溢油事故频繁发生,对各国经济的可持续发展形成相当大的威胁。
     随着高光谱遥感技术的发展,以及该技术在溢油区检测、油种识别、油膜厚度估计等方面的独特优势,高光谱海洋油膜遥感检测已经成为国内外关注的热点。
     论文以大连溢油和青岛溢油高光谱图像为研究背景,对现有的分类算法进行比较研究,并在此基础上针对地物特性对现有分类算法进行改进,最后,将改进的算法应用在溢油高光谱图像的分类处理中,得到了较好的分类效果。
     算法分析过程中的实验结果证明了论文所提分类算法的有效性,高光谱溢油图像分类系统的实现和处理结果,进一步说明了论文所提方法在高光谱图像处理中的可行性。
The oil spoil events occurred frequently in the last years, which makes it more and more important for the nations to detect and control the events because they do influence the maintaining develop of the countries.
     Hyperspectral detection of marine oil spill have been focused recently, because the development of hyperspectral technologies is amazing and it have absolutely advantages in region detecting, type identifying and thickness determining.
     Firstly, the current methods for classification are compared and discussed. Then, the improvement is made based on the current method considering the property of object spectral. At the last, the prompted algorithm is realized in the classifying system for hyperspectral oil spill images, which are from the spill event in Dalian and Qingdao. It came that the algorithm is good in performance.
     The experiments commit during the process of analysis shows the efficiency of the prompted algorithm. And the realization and results in the classifying system of hyperspectral oil spill image further the feasible of the method.
