Measurements and Scoring Procedures for Footwear Impression Comparisons



Martin Herman


A software system under development at NIST, called SHOECALC, will be described. It is designed to help both researchers and footwear examiners in the assessment of metrics or scoring procedures that provide objective characterizations of correspondences and discrepancies between features from two footwear impressions being compared. The presentation will provide the current status of the system, focusing on matching algorithms, similarity scores, and image quality metrics.
