GeneralizedProcrustesAnalysis

class menpo.transform.groupalign.procrustes.GeneralizedProcrustesAnalysis(sources, target=None)

Bases: MultipleAlignment

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

The target PointCloud to align each source to. If None, then the mean of the sources is used.

Default: None

Raises:

ValueError :

Need at least two sources to align

av_alignment_error

Returns the average error of the recursive procrustes alignment.

Type:float

mean_aligned_shape

Returns the mean of the aligned shapes.

Type:PointCloud
