¡ Overview

§ Program § ROOT, Python § Track Identification by finding projections

¡ Goal

§ Faster method of finding projections

§ Currently using Hough transform

§ (number of slopes)^2 or even ^3 running time

§ FT: Rays start at origin § Running time is proportional to number of slopes
