plenoptic.process.rescale#

plenoptic.process.rescale(x, a=0.0, b=1.0)[source]#

Linearly rescale the dynamic range of the input to [a, b].

Parameters:

  • x (Tensor) – Tensor to rescale.

  • a (float (default: 0.0)) – Min and max values, respectively, for the output.

  • b (float (default: 1.0)) – Min and max values, respectively, for the output.

Return type:

Tensor

Returns:

rescaled_x – The rescaled tensor.

Examples

>>> import plenoptic as po
>>> import torch
>>> x = torch.tensor([2.0, 4.0, 6.0, 8.0])
>>> po.process.rescale(x)
tensor([0.0000, 0.3333, 0.6667, 1.0000])
>>> po.process.rescale(x, a=-1, b=1)
tensor([-1.0000, -0.3333, 0.3333, 1.0000])
