Abstract
Disclosed herein are methods, apparatus, and systems for iris and periocular biometric recognition. A method for biometric recognition includes capturing one or more image frames of at least a facial portion of a user, determining an iris image portion and a periocular region image portion from the one or more image frames, performing iris encoding on a live iris image portion to generate an iris template, performing periocular region encoding on a live periocular region image portion to generate a periocular region template, performing iris matching on the iris template to generate an iris result, performing periocular region matching on the periocular region template to generate a periocular region result, and using one or more of the iris result and the periocular region result to enable the user to access an object.
