Face Recognition System under Varying Lighting Conditions

Making recognition more reliable under uncontrolled lighting conditions is one of the most important challenges for practical face recognition systems. Other recognition systems don’t nullify most of the lighting variations. We tackle this by combining the strengths of robust illumination normalization, local texture-based face representations, distance transform based matching and kernel based...

Physiologic anisocoria under various lighting conditions

Purpose To evaluate the measurement of anisocoria in a group of ocular healthy subjects using a standardized protocol in scotopic, mesopic, and photopic lighting conditions, and determine the optimal threshold of difference in pupil diameter in determining physiologic anisocoria. Methods Right and left pupil diameters of 126 ocular healthy subjects with a mean age 30.5±7.8 years (40 males and...

Object Recognition under Various Lighting Conditions

This paper describes object recognition under various lighting conditions for a robot which finds a user-specified object and brings it to the user. The system first constructs object models under a known lighting condition. Because the lighting condition in model construction is different from that in object recognition, the system needs to transform the model’s color for the current lighting ...
