56
+ ### Dataset Summary
57
+
58
+ 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).
59
+
60
+ Install with `pip`:
61
+ ```bash
62
+ pip install datasets super-image
63
+ ```
64
+
65
+ Evaluate a model with the [`super-image`](https://github.com/eugenesiow/super-image) library:
66
+ ```python
67
+ from datasets import load_dataset
68
+ from super_image import EdsrModel
69
+ from super_image.data import EvalDataset, EvalMetrics
70
+
71
+ dataset = load_dataset('eugenesiow/Set14', 'bicubic_x2', split='validation')
72
+ eval_dataset = EvalDataset(dataset)
73
+ model = EdsrModel.from_pretrained('eugenesiow/edsr-base', scale=2)
74
+ EvalMetrics().evaluate(model, eval_dataset)
75
+ ```
76
+
77
+ ### Supported Tasks and Leaderboards
78
+
79
+ The dataset is commonly used for evaluation of the `image-super-resolution` task.
80
+
81
+ Unofficial [`super-image`](https://github.com/eugenesiow/super-image) leaderboard for:
82
+ - [Scale 2](https://github.com/eugenesiow/super-image#scale-x2)
83
+ - [Scale 3](https://github.com/eugenesiow/super-image#scale-x3)
84
+ - [Scale 4](https://github.com/eugenesiow/super-image#scale-x4)
85
+ - [Scale 8](https://github.com/eugenesiow/super-image#scale-x8)

91
+ ## Dataset Structure
92
+
93
+ ### Data Instances
94
+
95
+ An example of `validation` for `bicubic_x2` looks as follows.
96
+ ```
97
+ {
98
+ "hr": "/.cache/huggingface/datasets/downloads/extracted/Set14_HR/baboon.png",
99
+ "lr": "/.cache/huggingface/datasets/downloads/extracted/Set14_LR_x2/baboon.png"
100
+ }
101
+ ```
102
+
103
+ ### Data Fields
104
+
105
+ The data fields are the same among all splits.
106
+
107
+ - `hr`: a `string` to the path of the High Resolution (HR) `.png` image.
108
+ - `lr`: a `string` to the path of the Low Resolution (LR) `.png` image.
