Bag of Soft Biometrics for Person Identification New Trends and Challenges
In this paper, the authors seek to provide insight on the general topic of soft biometrics. They firstly present a new refined definition of soft biometrics, emphasizing on the aspect of human compliance, and then proceed to identify candidate traits that accept this novel definition. They, then address relations between traits and discuss associated benefits and limitations of these traits. They also consider two novel soft biometric traits, namely weight and color of clothes and they analyze their reliability. Related promising results on the performance are provided. Finally, they consider a new application, namely human identification solely carried out by a bag of facial, body and accessory soft biometric traits, and as an evidence of its practicality, they provide preliminary promising results.
