A COMPARATIVE STUDY OF EXAMINATION TECHNIQUES FOR TOOL MARKS IDENTIFICATION

Abstract

Comparing tool marks to help solve crimes is a well-known and popular
technique that is typically regarded as soft valid evidence in court. The
features which impact the characters of marks left by tool & which must be
considered in the identification of such marks. The programme MANTIS, or
Manipulative Toolmark Inspection Suite, aids in distinguishing between
various tool kinds. Made by Alicona, GmbH, it is a portable 3-D optical
profilometer. A kinematic model is used by the integrated system GE/2 to
explain the groove generating process. The (TRAX) Tool Mark Imaging System
Database device is intended for the acquisition, preservation, and comparison
of tool pictures with the width and kind of tool mark indicated by their textual
descriptors. Analytical statistics SVMs aid in distinguishing between different
tool kinds.
The primary uses of micro-CT scanning include saw mark analysis, statistical
analysis for tool differentiation, toolmark width determination based on tool
blade width, and various toolmarks created under various methodological
settings such as the presence of flesh and tissue. The present study is
concerned with the comparison of examination technique used in the tool
marks for the identification of the tool mark impression.
