Research on Recognition of Landslides with Remote Sensing Images Based on Extreme Learning Machine
Hui Xu, Xiang Li, Wenyin Gong · 2017
The geological disasters of landslides induced by the Wenchuan earthquake are great in number so landslide disaster recognition and investigation must be conducted in the early stage of large construction planning in the disaster area. In recent years, the studies on image recognition focus on the extreme learning machine algorithm. Based on the preprocessing of remote sensing images, this paper conducts landslide recognition with remote sensing images through the extreme learning machine classification combined with color and texture features of ground objects. The comparison experiments of landslide recognition with the support vector machine algorithm shows that the recognition accuracy of the ELM algorithm is not much different from that of the SVM algorithm, but the extreme learning machine takes short time in training with absolute advantage.
