Fast illumination normalization for robust eye localization under variable illumination

摘要

Most eye localization methods suffer from illuminationnvariation. To overcome this problem, we propose an illumination nor-nmalization technique as a preprocessing step before localizing eyes.nThis technique requires no training process, no assumption on thenlight conditions, and no alignment between different images for illu-nmination normalization. Moreover, it is fast and thus effective fornreal-time applications. Experiment results verify the effectivenessnand efficiency of the eye localization scheme with the proposed illu-nmination normalization technique.
