Shape Analysis for Planar Barefoot Impression.

The shape or outlines of planar barefoot impressions of persons has been found useful in many cases for personal identification. This paper performs an automatic analysis on the shape of barefoot impressions, totally 28 numerical feature measurements are extracted to describe the geometry and structure properties of the barefoot impression's shape. Each measurement on the footprint outlines extracted in this work is examined for the distinguishability and the consistence by its population standard deviation versus interpersonal standard deviation ratio (SDR). Experiment result shows that we can obtain feature measurements from barefoot impression images reliably. [ABSTRACT FROM AUTHOR]
