Facial recognition of identical twins

Abstract

Biometric identification systems must be able to distin guish between individuals even in situations where the bio metric signature may be similar, such as in the case of iden tical twins. This paper presents experiments done in facial recognition using data from a set of images of twins. This work establishes the current state of facial recognition in regards to twins and the accuracy of current state-of-the art programs in distinguishing between identical twins us ing three commercial face matchers, Cognitec 8.3.2.0, Ver iLook 4.0, and PittPatt 4.2.1 and a baseline matcher em ploying Local Region PCA. Overall, it was observed that Cognitec had the best performance. All matchers, how ever, saw degradation in performance compared to an ex periment where the ability to distinguish unrelated persons was assessed. In particular, lighting and expression seemed to have affected performance the most.

Facial aging and asymmetry decomposition based approaches to identification of twins

“…However, experiments conducted by Daugman and Downing in 5 [2], by Jain et al in [3], by Srihari et al in [4], and by Kong et al in [5] have shown that biometric identifiers such as the iris, fingerprints, and palmprints can be used to tell identical twins apart. Recently, studies carried out in [6], [7], [8], [9], [10], [11] have also proved that facial features and facial recognition systems can be used to tell identical twins apart. However, to the best of our knowledge, no study has yet been 10 carried out in order to analyze the use of facial aging features and asymmetry decomposition features in distinguishing identical twins.…”

It is our aim to extend the study of using facial features to distinguish twins by carrying out comprehensive tests on a large database in order to demonstrate the effectiveness of our proposed approaches and highlight possible areas of improvement in this emerging field.…”

“…However, some studies, such as those described in [6], [7], [8], [9], [10], and [11], have shown that facial recognition of identical twins is quite possible. Biswas et al investigated the human ability to distinguish identical twins in [6].…”

Family Relationship Analysis In Photos

“…Meanwhile, there are some researchers trying to investigate the familial traits between twins [33,34]. Some of them also analyzed the performance of face recognition between twins [35]. Actually, twins belong to the same family, but their familial traits are more similar than other family members.…”

“…This step is to nd the stable key points. Then the author referred to the work proposed by Brown and Lowe [35], they used a scheme for tting a 3D quadratic function. This function interpolated the location maximum in local sample points.…”
