pyFM.eval.evaluate.accuracy(p2p, gt_p2p, D1_geod, return_all=False, sqrt_area=None)

Compute the geodesic accuracy of a vertex to vertex map.

The map goes from the target shape to the source shape.

Parameters:

  • p2p ((n2,) np.ndarray) – Vertex to vertex map giving the index of the matched vertex on the source shape for each vertex on the target shape (from a functional map point of view).

  • gt_p2p ((n2,) np.ndarray) – Ground truth mapping between the pairs.

  • D1_geod ((n1, n1) np.ndarray) – Geodesic distance between pairs of vertices on the source mesh.

  • return_all (bool, optional) – Whether to return all the distances or only the average geodesic distance.

  • sqrt_area (float, optional) – If provided, the square root of the mesh area used to normalize the distances.

Returns:

  • acc (float) – Average accuracy of the vertex to vertex map.

  • dists ((n2,) np.ndarray) – Only if return_all is True - all the pairwise distances.
