利用高空间分辨率影像,采用面向对象的分类方法,通过多种方法确定了土地利用类型的适宜尺度,形成了多尺度的影像对象层次网络体系。对影像对象进行多特征与空间关系描述,有效集成了辅助特征和专家知识,构建了影像对象分类规则集。研究区分类结果表明:地物分布特征及其空间关系规则的应用,可以有效地提高分类精度,得到更好的语义区分和更精确的分类结果。以期仅作少许改动就可将方案应用到条件类似的高分辨率影像分类中。 更多还原

【Abstract】 The high spatial resolution images are used and object-oriented classification method is adopted to determine the appropriate scale of land use types by various methods and the hierarchical network system of image object with multi-scale are obtained.The features and spatial relationship of image objects are derived,the auxiliary characteristic and the expert knowledge summarized effectively and build the classification rules set of image objects.The results of the classification indicate that t... 更多还原
