Multi-source remote sensing image classification method based on robust deep semantic segmentation network

Abstract

The invention discloses a multi-source remote sensing image classification method based on a robust deep semantic segmentation network (Robust Loss Function of Remote Sensing Imagery, RSRLF). The method is formed by recombining a fault tolerance loss function and an adaptive category weight. Remote sensing semantic segmentation is carried out based on the open source land cover classification dataset so that sample annotation work can be greatly reduced, but the open source land cover classification data set contains a certain annotation error sample. The method is advantaged in that the fault tolerance loss function can inhibit the model from learning the noise label, and avoids the over-fitting of the noise label by the model; and a category equalization constraint module can solve problems of large scale difference of globally distributed samples of ground object categories and inconsistent confusion degree among the categories; combination of the two can effectively solve a problem that noise labels and category samples are unbalanced when remote sensing semantic segmentation is carried out by using an open source land cover classification data set, and ground object classification precision based on an open source land cover classification data set is improved.
