bb_avg_edge_length

menpofit.error.bb_avg_edge_length(shape)

Computes the average edge length of the bounding box of the provided shape, i.e.

\[\frac{h + w}{2} = \frac{2h + 2w}{4}\]

where \(h\) and \(w\) are the height and width of the bounding box.

Parameters

shape (menpo.shape.PointCloud or subclass) – The input shape.

Returns

bb_avg_edge_length (float) – The average edge length of the bounding box.
