Super Resolution Generative Adversarial Network Based Image Augmentation for Scene Classification of Remote Sensing Images

Abstract

High spatial resolution remote sensing image (RSI) scene classification, aimed at automatically labelling images with the given semantic categories, has been a hot issue. As it's difficult for RSI to quickly obtain a large number of training samples from a specific area. Traditional scene classification researches were mainly using deep learning models to transfer natural images to RSI. Considering the differences between natural images and RSI, we trained several Super Resolution GAN models by using different resolution RSI data from Google earth image. This paper proposed a novel SRGAN-CNN framework. Through transferring the data with scene classification dataset to obtain high resolution fake RSI. The experimental results demonstrate that the proposed framework can enhance transfer effect and help improve the accuracy of scene classification using low resolution RSI.
