| Abstract: | A new mainstream feature extraction approach is proposed, which efficiently fuses the two main manifestations in remote sensing images: spectral features and spatial information. The approach depicts the spatial structm-es with the relationships between pixels and their neighborhoods, and describes the main-stream with the direction line. Finally, the position and trend of the main-stream line are achieved. The experiments results show that the presented approach is com-petent for main-stream feature extraction and the feature could be extracted effectively. |
