Poster, 12th Annual Canadian Conference on Intelligent Systems (IRIS), Calgary, Canada, May 2002.

Abstract

This poster proposes a technique for the measurement of lateral skin stretch on the fingertip. A sequence of images is acquired as the fingertip moves across a transparent surface. Fingerprint minutia are detected using techniques borrowed from the fingerprint identification field (Stosz and Alyea, 1994) and tracked between pairs of successive images. Variations in inter-minutia distance are used to evaluate lateral skin stretch.
