Abstract:

?提出了高分辨率遥感影像中阴影的检测与补偿的全自动处理方法.首先,利用简单阴影特征构造复合特征的方法联合构建多种光谱阈值检测条件,结合相应自动阈值获取方案实现阴影自动初检测,并设计自动形态学处理方法对初检测结果进行后处理;然后,以补偿模型为基础,通过统计阴影与非阴影区域的亮度均值与均方差、采用特征点提取与匹配的方法自动获取模型参数,再综合区域级整体补偿和窗口级局部补偿两种结果实现阴影的全自动补偿.结果表明,多条件联合检测与自动形态学处理可提升检测结果的总体精度和区域完整性,补偿模型参数自动获取方法可靠有效,综合补偿法充分结合整体与局部补偿的优势,提升整体亮度,突显纹理细节,使得被阴影遮挡的信息得以真实再现.
