FORENSIC COMPARISON OF FACIAL IMAGES OF DOPPELGÄNGERS

Abstract

The paper examines the problem of forensic examination of doppelgängers' portraits for dominant matching features. The authors outline the types of forensic objectives addressed in the course of such examination, and offer an algorithm for the selection of matching group, individualizing and dominant characteristics (features) in doppelgängers' facial images. The relationship between individualizing and dominant features is analyzed, and the concept of a dominant set of features is introduced. Recommendations are offered for the best methods of dominant feature identification.
