- •
A new method named congruent matching cross-sections (CMX) is proposed.
- •
Each firing pin impression is sliced into layers alongside circular cross-sections.
- •
A differential profile method is applied to convert the cross-sections to profiles.
- •
Correlation function is used for quantifying similarity of the pair-wise profiles.
- •
Three parameters are used to determine the congruency of the correlated impressions.
