Abstract Complex scene classification has great significance for mining the value information in remote sensing images. The proposed convolutional neural networks (CNN) can improve the complex scene classification of remote sensing images. The CNN method extracts features automatically, avoiding problems in the image pretreatment and the feature extraction by manual labor. An eight-layer CNN model is constructed in this paper, and the pre-treatment module has enhanced the adaptability of this method. Given the problem in choosing classifiers, this paper provides the Softmax and support vector machine (SVM) in the presented CNN. The experiment results in two datasets, the UC Merced Land Use and the Google of SIRI-WHU indicate that the presented CNN method can increase the accuracy of classification by more than 2% compared with the CNN with Overfeat feature method and the SRSCNN method, and the total classification accuracy of the two classifiers is over 95%.
