Functions

random_2d_perlin(→ Union[numpy.ndarray, torch.Tensor])

Returns a random 2d perlin noise array.
anomalib.data.utils.generators.random_2d_perlin(shape: Tuple, res: Tuple[Union[int, torch.Tensor], Union[int, torch.Tensor]], fade=lambda t: ...) → Union[numpy.ndarray, torch.Tensor][source]

Returns a random 2d perlin noise array.

Parameters

  • shape (Tuple) – Shape of the 2d map.

  • res (Tuple[Union[int, Tensor]]) – Tuple of scales for perlin noise for height and width dimension.

  • fade (_type_, optional) – Function used for fading the resulting 2d map. Defaults to equation 6*t**5-15*t**4+10*t**3.

Returns

Random 2d-array/tensor generated using perlin noise.

Return type

Union[np.ndarray, Tensor]
