noisy_align

menpo.fitmultilevel.functions.noisy_align(source, target, noise_std=0.04, rotation=False)

Constructs and perturbs the optimal similarity transform between source to the target by adding white noise to its weights.

Parameters:

source: :class:`menpo.shape.PointCloud` :

The source pointcloud instance used in the alignment

target: :class:`menpo.shape.PointCloud` :

The target pointcloud instance used in the alignment

noise_std: float :

The standard deviation of the white noise

Default: 0.04

rotation: boolean :

If False the second parameter of the Similarity, which captures captures inplane rotations, is set to 0.

Default:False

Returns:

noisy_transform : :class: menpo.transform.Similarity

The noisy Similarity Transform
