摘要
应用Pan-sharpen ing和G ram-Schm id两种高保真融合影像方法对A los全色光谱影像和多光谱影像进行融合,并且对融合效果进行评价和分析,选取结果较优的G ram-Schm idt方法融合后的影像作为面向对象方法提取影像的数据源进行水体的提取。检验最后的提取结果,发现面向对象的方法在融合后的影像中提取水体,可得到较好结果。
The paper applied the Pan-sharpening and Gram-Schmid image fusion methods to fuse the Alos multispectral image and panchromatic band image,and then comparing the results chose the better one for extract the water from the image.Object-oriented information extraction method was used to extract the water bodies,the results found that this method can be adopted for water extraction.
