Harin Sellahewa & Sabah Jassim, “Image quality-based adaptive illumination normalisation for face recognition”, Proceedings of SPIE vol.7306B: Biometric Technology for Human Identification VI (2009). ISBN: 978-0-8194-7572-5.

This paper was given at the SPIE Defense, Security and Sensing conference, April 2009, Orlando, Florida, USA, and has now been published. It presents a dynamic approach to illumination normalisation, based on face image quality. The quality of a given face image is measured in terms of its luminance distortion by comparing this image against a known reference face image. Histogram equalisation is applied to a probe image if its luminance distortion is higher than a predefined threshold. The authors tested the proposed adaptive illumination normalisation method on the widely used Extended Yale Face Database B. Identification results demonstrate that their adaptive normalisation produces better identification accuracy compared to the conventional approach where every image is normalised, irrespective of the lighting condition in which they were acquired.
