+# TD 02: Urban Surface Textures
+
+This dataset contains multi-photo texture captures in outdoor nature scenes — many focusing on the ground and the others are walls.  Each set has different photos that showcase texture variety, making them ideal for training a domain-specific image generator!
+
+Overall information about this dataset:
+
+* **Format** — JPEG-XL, lossless RGB
+* **Resolution** — 4032 × 2268
+* **Device** — mobile camera
+* **Technique** — hand-held
+* **Orientation** — landscape
+* **Author**: Alex J. Champandard
+* **Configurations**: 4K, 2K (default), 1K
+
+To load the medium- and high-resolution images of the dataset, you'll need to install `jxlpy` from [PyPI](https://pypi.org/project/jxlpy/) with `pip install jxlpy`:
+
+```python
+# Recommended use, JXL at high-quality.
+from jxlpy import JXLImagePlugin
+from datasets import load_dataset
+d = load_dataset('texturedesign/td02_urban-surface-textures', 'JXL@4K')
+
+print(len(d['train']), len(d['test']))
+```
+
+The lowest-resolution images are available as PNG with a regular installation of `pillow`:
+
+```python
+# Alternative use, PNG at low-quality.
+from datasets import load_dataset
+d = load_dataset('texturedesign/td02_urban-surface-textures', 'PNG@1K')
+
+# EXAMPLE: Discard all other sets except Set #1.
+dataset = dataset.filter(lambda s: s['set'] == 1)
+# EXAMPLE: Only keep images with index 0 and 2.
+dataset = dataset.select([0, 2])
+```
+
+Use built-in dataset `filter()` and `select()` to narrow down the loaded dataset for training, or to ease with development.
