# Dataset Description

This is the training dataset for our AAAI2024 paper [Iterative Token Evaluation and Refinement for Real-World Super-Resolution](https://arxiv.org/abs/2312.05616).  
You may use this dataset with our released codes in [Github](https://github.com/chaofengc/ITER).

The datasets contains sub-image pairs of (LQ, HQ) patches.
- HQ_subimages: high quality image patches extracted from DIV2K, DIV8K, Flicker2K, OutdoorSceneTraining and FFHQ.
- LQ_subimages_X2: low quality patches with x2 downsampling
- LQ_subimages_X4: low quality patches with x4 downsampling

Please see more details in the paper.
