Preliminary Study on the Uniqueness of Barefoot Impressions

Pages 233-238 | Published online: 22 Nov 2013
 

ABSTRACT

This paper describes a study to determine the uniqueness of barefoot impressions. A computer based search process has been developed in an attempt to demonstrate that the morphology of a human foot creates an impression that is unique to that individual. Using inked barefoot impressions from volunteers, the computer search uses 38 different measurements taken for each pair of feet. Searches through the present database of more than 3800 impressions, produced a possible match only when the print being searched is already in the data base. In these cases, a visual examination of the “matched” foot prints was sufficient to determine that they were from the same individual. The results to date, therefore, are consistent with the idea of the uniqueness of barefoot impressions.

RÉSUMÉ

Cet article décrit une étude sur l'individualité des impressions plantaires. Nous avons développé un système informatisé, cherchant à démontrer que la morphologie d'un pied humain crée des impressions uniques à l'individu. À partir d'impressions encrées obtenues de volontaires, le système informatisé analyse 38 variables différentes mesurées pour chaque paire de pieds. En se référant à une base de données de plus de 3800 impressions, le système informatisé ne repéra des concordances que lorsque l'impression était déjà dans la base de données. Dans ces circonstances, un examen visuel des impressions concordantes était suffisant pour établir qu'elles provenaient du même individu. Les résultats, jusqu'à présent, supportent le concept de l'individualité des impressions plantaires.
