bullets

A dataset containing pre-processed information of two bullets. They are used
as examples in Chapter 3.5 of Open Forensic Science in R.

This is an open-source implementation of the Congruent Matching Profile
Segments (CMPS) method (Chen et al. 2019)<doi:10.1016/j.forsciint.2019.109964>.
In general, it can be used for objective comparison of striated tool marks, and in our
examples, we specifically use it for bullet signatures comparisons. The CMPS score is
expected to be large if two signatures are similar. So it can also be considered as a
feature that measures the similarity of two bullet signatures.
