A Scene Semantic Recognition Method of Remote Sensing Images Based on CSIFT and PLSA

Aiming at the fast recognition of local image scenes with clear semantics in high-resolution remote sensing images, such as ports, airports and oil depots, a visual feature representation method for remote sensing images based on CSIFT features and a scene semantic recognition method based on PLSA is proposed. Experiments on typical remote sensing image scenes fully verify the effectiveness of proposed method.
