GeneralizedProcrustesAnalysis¶

class menpo.transform.GeneralizedProcrustesAnalysis(sources, target=None, allow_mirror=False)[source]¶

Class for aligning multiple source shapes between them.

After construction, the AlignmentSimilarity transforms used to map each source optimally to the target can be found at transforms.

Parameters

sources (list of PointCloud) – List of pointclouds to be aligned.
target (PointCloud, optional) – The target PointCloud to align each source to. If None, then the mean of the sources is used.
allow_mirror (bool, optional) – If True, the Kabsch algorithm check is not performed, and mirroring of the Rotation matrix is permitted.

Raises

ValueError – Need at least two sources to align

mean_aligned_shape()[source]¶

Returns the mean of the aligned shapes.

mean_alignment_error()[source]¶

Returns the average error of the recursive procrustes alignment.
