Quantitative Measures in Support of Latent Print Comparison.

摘要

Latent prints of friction ridge impressions have long been useful in identication, and the methodology of examining latent prints, known as ACE-V (analysis, comparison, evaluation and verication), has been welldocumented. The need to quantify condences within ACE-V has been articulated in several recent in uential reports to strengthen the science of friction ridge analysis. This research addresses the evaluation of three quantitative measures: rarity of features, condence of opinion and a probabilistic measure of similarity. The rst of these, useful in the analysis phase of ACE-V, is to determine the rarity of observed features.
