Abstract: | This paper focused on BP neural networks which was notable in the classification of remote sensing image processing application, and researched BP neural network classification algorithm in Matlab software platform. Finally, the classification was compared with supervised classification results under ERDAS software platform. The results show that BP neural network-based remote sensing image classification is more precise than the supervision of the general classification which under the total ERDAS software platform. It is an effective method of remote sensing image classification. |
