mdreg.defo_norm#
- mdreg.defo_norm(defo, norm='euclidian')[source]#
Calculate the norm of a deformation field.
- Parameters:
defo (np.ndarray) – The deformation field to calculate the norm from. Dimensions are expected in the order [x, y, z, d, t], where x, y, z are the spatial dimensions, d is the dimension of the deformation field (two for 2D registration, 3 for 3D registration), and t is the time/dynamic.
norm (str) – The type of norm to use. Options are ‘euclidian’, ‘max’ or ‘eumax’. The latter is the maximum projection over time of the euclidian norm. Default is ‘euclidian’.
- Returns:
norm – The norm of the deformation field with dimensions [x, y, z, t].
- Return type:
np.ndarray
