This paper presents a solution to automatically recognize the correct left/right and upright/upside-down orientation of iris images. This solution can be used to counter spoofing attacks directed to generate fake identities by rotating an iris image or the iris sensor during the acquisition. Two approaches are compared on the same data, using the same evaluation protocol: 1) feature engineering, using...
Automatically detecting novel types of cosmetic contact lenses in iris images is a very difficult pattern-recognition problem, but experimental datasets that enable researchers to study this problem have recently become available.
