Image processing for the positive identification of forensic ballistics specimens
نویسنده
چکیده
The need for firearm identification systems by police services continues to increase with greater accessibility to weapons in the national and international contexts. The difficulties associated with traditional imaging of ballistics specimens are numerous, and include the smallness of the samples, the nature of the surfaces and shapes for the cartridge cases and projectiles. The “mechanical fingerprint” on fired bullets and cartridge cases can be used to identify the firearm that they passed through. A PC based firearm identification system, Fireball, has been developed at Edith Cowan University and used by police ballistics sections in Australia. This paper will give a brief description of this system and details of the image processing such as segmentation, feature extraction and image processing before saving images to the image database. Examples will be given to demonstrate the methodology.

Abstract Over the last two decades, improvements in developing computational tools made significant contributions to the classification of biological specimens` images to their correspondence species. These days, identification of biological species is much easier for taxonomist and even non-taxonomists due to the development of automated computer techniques and systems. In this study, we d...
متن کاملFeatures Extraction and Classification of Cartridge Images for Ballistics Identification
Ballistics identification is a quite challenging task from both theoretical and practical point of view. The premise underlying firearms and toolmark identification is that each firearm owns its unique toolmarks, resulting in some unique characteristic markings left on the fired projectile and cartridge case. Although various techniques have been applied to firearm identification, the major pro...

The National Institute of Standards and Technology (NIST) has proposed a “NIST Ballistics Identification System (NBIS)” to facilitate accurate ballistics identifications and fast evidence searches [1]. The NBIS will use three-dimensional (3D) topography measurements for ballistics identification and evidence searches. The 3D topographies will be subdivided into arrays of correlation cells in or...
متن کاملSome Forensic Aspects of Ballistic Imaging
Analysis of ballistics evidence (spent cartridge casings and bullets) has been a staple of forensic criminal investigation for almost a century. Computer-assisted databases of images of ballistics evidence have been used since the mid-1980s to help search for potential matches between pieces of evidence. In this article, we draw on the 2008 National Research Council Report Ballistic Imaging to ...
