vreg.Volume3D#
- class vreg.Volume3D(values: ndarray, affine: ndarray)[source]#
A spatially aware numpy array
- Parameters:
values (np.ndarray) – 2D or 3D numpy array with values
affine (np.ndarray) – 4x4 numpy array with the affine matrix of the value array. If not provided, the identity is assumed. Defaults to None.
