说明：  一个溢油检测算法，先检测暗区目标，再进行特征提取，然后分类识别
(We present algorithms for automatic detection of oil spills in synthetic aperture radar (SAR) images. The algorithms consist of three main parts, namely: 1) detection of dark spots 2) feature extraction from the dark spot candidates and 3) classification of dark spots as oil spills or look-alikes.)
