In this work, we propose a compact multi-task architecture based on deep learning for remote sensing scene classification and image quality assessment (IQA) simultaneously. The model can be trained in an end-to-end manner, and the robustness of classification is improved in our method. More importantly, by exploiting IQA and super-resolution, the accurate classification results can be obtained even if the images are distorted or with low quality. To the best of our knowledge, it is the first successful attempt to associate IQA with scene classification in a unified multi-task architecture. Our method is evaluated on the expanded UC Merced Land-Use dataset after data augmentation. In comparison with some other methods, the experimental results show that the proposed structure makes a great improvement on both classification and IQA.
