AUTOMATED BALLISTIC
IDENTIFICATION SYSTEM Automated Ballistic Identification Systems (ABIS) are
specialized computer hardware/software combinationsdesigned to capture, store and rapidly compare digital imagesof bullets and cartridge casings.
ABIS have four key components: The Ballistic Scanner, which captures the images of the bullets
and cartridges
The Signature Extraction Unit, which uses amathematical algorithm to extract unique signatures from the
images Data Storage Unit, which serves as the main storage,
The Correlation Server, which handles the actual comparison ofimages.
