Abstract
Pupil dilation is shown to degrade iris recognition accuracy (Hollingsworth et al., 2009, [7]) by increasing the Hamming distance between genuine samples thereby increasing the false reject rate (FRR). Dilation of pupil due to illumination changes or drugs results in complex deformation of the iris texture. In this work, a database to study the effect of pupil dilation is acquired. The adverse effect of pupil dilation on iris recognition is demonstrated using this database. A novel fusion scheme that ...
