deepmr.recon.intensity_scaling

deepmr.recon.intensity_scaling(input, ndim)

Rescale intensity range of the input image.

This has the main purpose of enabling easier tuning of regularization strength in interative reconstructions.

Parameters:

• input (np.ndarray | torch.Tensor) – Input signal of shape (..., ny, nx) (2D) or (..., nz, ny, nx) (3D).

• ndim (int, optional) – Number of spatial dimensions.

Returns:

output – Rescaled signal.

Return type:

np.ndarray | torch.Tensor.
