Abstract: In order to overcome the defects that extracts rivers sample with spectrum information, using high-resolution remote sensing satellite imagery of the outstanding features of high resolution, a method of comprehensive satellite image feature is put forward, including spectrum, texture, geometric features and so on. It is a method that extracts river with joint features. The rivers spectral features, texture features and geometric shape features are described respectively. By selecting characteristic parameters, structure integrated characteristic matrix, this paper reuses the average clustering segmentation, and eventually gets river target. The real high-resolution remote sensing images Worldview1 experiments validate the preciseness and rapidity of the methods.
