Ballistics Image Processing and Analysis for Firearm Identification [chapter]

Dongguang Li
2009 Image Processing  
A hierarchical neural network is used to create a firearm identification system based on cartridge case images. We focus on the cartridge case identification of rim-fire mechanism.  ...  In this section a proposed hierarchical firearm identification model based on cartridge cases images is shown.  ...  Ballistics Image Processing and Analysis for Firearm Identification, Image Processing, Yung-Sheng Chen (Ed.), ISBN: 978-953-307-026-1, InTech, Available from: http://www.intechopen.com/books/image-processing  ...

Vibrational spectroscopy and chemometrics in GSR: review and current trend

Bharti Jain, Poonam Yadav
2021 Egyptian Journal of Forensic Sciences  
Short conclusion As a final point, the end of part of this review deals with the applicability of chemometric methods in forensic ballistics.  ...  We select to give an elaborate description of many significant tools established with their algorithm in admire of utilizing and accepting them by researchers not very aware with chemometrics.  ...  Weber and his co-workers researched on metal organic frameworks (MOFs) and based on this they differentiate luminescent markers in ammunition for identification of GSR from non-toxic ammunition.  ...

Quantitative profile–profile relationship (QPPR) modelling: a novel machine learning approach to predict and associate chemical characteristics of unspent ammunition from gunshot residue (GSR)

Matteo D. Gallidabino, Leon P. Barron, Céline Weyermann, Francesco S. Romolo
2019 The Analyst  
Possibility to associate gunshot residues with other residues or their original ammunition has been demonstrated using a novel predictive approach.  ...  The authors would like to thank Rachel Irlam (King's College London, UK) for proof-reading the document.  ...  an investigation (as, for example, a spent cartridge case with a reference ammunition or entry hole) may provide law-enforcement authorities with crucial intelligence and scientific evidence. 2, 3 As  ...
