This is an implementation of the Kobyshev score from the 3DV 2016 paper.
This is only the initial score, the refined score code is pending...

3D Saliency for Finding Landmark Buildings, 3DV 2016
N. Kobyshev, H. Riemenschneider, A. Bodis-Szomoru, L. Van Gool

The code takes a 3D pointcloud (.ply) and calculates the Kobyshev score
as described in Eq. 2 to measure the 3D saliency.
The output are the KNNs, the score, a visualization and the features.
