Detailed Description

Cluster finding and building.

Cluster reconstruction namespace.

2D end point reconstruction

The algorithm is based on: C. Harris and M. Stephens (1988). "A combined corner and edge detector". Proceedings of the 4th Alvey Vision Conference. pp. 147-151. B. Morgan (2010). "Interest Point Detection for Reconstruction in High Granularity Tracking Detectors". arXiv:1006.3012v1 [physics.ins-det]
