FACIAL SOFT BIOMETRICS - Library of Ph.D. Theses | EURASIP

917.5 SummaryThis chapter presented classification algorithms related to six facial soft biometric traits, namelythe color of eye, skin and hair and moreover beard, moustache and glasses and provide accordingresults. We then specifically focused on and examined eye color, developed an automatic eyeclassification system and studied the impact of external factors on the appearance of eye color. Wehave identified and illustrated color shifts due to variation of illumination, presence of glasses, thedifference of perception of left and right eye, as well as due to having two different camera sensors.In the last chapter 8 we deviate from the analysis and development point of view towards SBSand examine instead the user friendliness of such a system by providing a study on user acceptancetowards such systems. In this study we compare SBSs to other biometric systems, as well as tothe classical PIN system toward access control.
