摘要 根据河流具有明显河道信息的特点,采用基于改进的Canny算子边缘提取方法从ETM+图像中提取河流湿地信息。试验表明,该方法综合利用了河流湿地的光谱特征和结构特征,取得较好效果。 Based on the linear features, the authors extracted river wetland information from ETM^+ image by using the method of advanced Canny edge extraction. Making use of both spectral and structural features of river wetland, this method acquired a good result.
