An algorithm to compare two‐dimensional footwear outsole images using maximum cliques and speeded‐up robust feature
Footwear examiners are tasked with comparing an outsole impression (Q) left at a crime scene with an impression (K) from a database or from the suspect’s shoe. We propose a
Statistical Learning Algorithms for Forensic Scientists
The goals of this workshop are to: (1) introduce attendees to the basics of supervised learning algorithms in the context of forensic applications, including firearms and footwear examination and trace
Similarity between outsole impressions using SURF
The learning objectives of this presentation include the following: Introduce an objective method to quantify the similarity between two outsole impressions, show that this algorithm is accurate and reliable even
