Dataset Preparation

The datasets used in this paper is WorldView-3 (can be downloaded here), QuickBird (can be downloaded here) and GaoFen-2 (can be downloaded here). Due to the copyright of dataset, we can not upload the datasets, you may download the data and simulate them according to the paper.

Get Started

Training and testing codes are in 'codes/'. Pretrained model can be found in 'codes/pretrained/'. All codes will be presented after the paper is completed published. Please refer to codes/how-to-run.md for detail description.
