Abstract

A database for toolmarks (named TRAX) has been developed on a PC with Microsoft Windows. The database is filled with video-images and administrative data about the toolmarks (width, kind of toolmark, etc.). A comparison screen in TRAX makes it possible to compare images of toolmarks.

The system works with the Screen Machine multi media-board. A new algorithm for the automatic comparison of digitized striation patterns has been developed. The algorithm works well for deep and complete striation marks and will be implemented in TRAX.

Keywords:
