+- **Repository**: https://huggingface.co/datasets/eugenesiow/Set14
+- **Paper**: http://www.cs.technion.ac.il/users/wwwb/cgi-bin/tr-get.cgi/2010/CS/CS-2010-12.pdf

+
+### Dataset Summary
+
+Set14 is an evaluation dataset with 14 RGB images for the image super resolution task. It was first used as the test set of the paper "On single image scale-up using sparse-representations" by [Zeyde et al. (2010)](http://www.cs.technion.ac.il/users/wwwb/cgi-bin/tr-get.cgi/2010/CS/CS-2010-12.pdf).
+
+Install with `pip`:
+```bash
+pip install datasets super-image
+```
+
+Evaluate a model with the [`super-image`](https://github.com/eugenesiow/super-image) library:
+```python
+from datasets import load_dataset
+from super_image import EdsrModel
+from super_image.data import EvalDataset, EvalMetrics
+
+dataset = load_dataset('eugenesiow/Set14', 'bicubic_x2', split='validation')
+eval_dataset = EvalDataset(dataset)
+model = EdsrModel.from_pretrained('eugenesiow/edsr-base', scale=2)
+EvalMetrics().evaluate(model, eval_dataset)
+```
+
+### Supported Tasks and Leaderboards
+
+The dataset is commonly used for evaluation of the `image-super-resolution` task.
+
+Unofficial [`super-image`](https://github.com/eugenesiow/super-image) leaderboard for:
+- [Scale 2](https://github.com/eugenesiow/super-image#scale-x2)
+- [Scale 3](https://github.com/eugenesiow/super-image#scale-x3)
+- [Scale 4](https://github.com/eugenesiow/super-image#scale-x4)
+- [Scale 8](https://github.com/eugenesiow/super-image#scale-x8)
+
+### Languages
+
+Not applicable.
+
+## Dataset Structure
+
+### Data Instances
+
+An example of `validation` for `bicubic_x2` looks as follows.
+```
+{
+    "hr": "/.cache/huggingface/datasets/downloads/extracted/Set14_HR/baboon.png",
+    "lr": "/.cache/huggingface/datasets/downloads/extracted/Set14_LR_x2/baboon.png"
+}
+```
+
+### Data Fields
+
+The data fields are the same among all splits.
+
+- `hr`: a `string` to the path of the High Resolution (HR) `.png` image.
+- `lr`: a `string` to the path of the Low Resolution (LR) `.png` image.
+
+### Data Splits
+
+| name  |validation|
+|-------|---:|
+|bicubic_x2|14|
+|bicubic_x3|14|
+|bicubic_x4|14|
+
