openalea.phenomenal.tracking.median_stem.get_median_polyline(polylines, n_stem_min=0, dz=2)[source]#

Returns a median polyline on the z axis

Parameters:

polylines (list) – list of 3D polylines
n_stem_min (int) – This parameters determines the maximum height of the median polyline : median polyline is only computed at height z if at least n_stem_min polyline have a max height > z.
dz (float) – space between two successive points of the median polyline on z axis.

Returns:

3D median polyline

Return type:

2D array
