Skateboard Decks

Skateboard Decks

This dataset contains around 2,000 images of skateboard decks.

The default image size is 128x128, but you can also specify different size during training, e.g with a relativitic GAN:

mantra train relativistic_gan --dataset decks --image-dim 256 256

In the data processing logic, vertical and horizontal flipping have been applied as data augmentation.


To import this dataset to your project, run:

mantra import RJT1990/data/decks


Example usage in code:

from import SkateboardDecks d = SkateboardDecks() print(d.X.__class__) ## <class 'numpy.ndarray'> print(d.X.shape) ## (5680, 128, 128, 3)
