Pomperada, Pinzhoffer, Tantipitham, Collins, Warren S. Warren · 2017
An analysis of face images was done to determine if a correlation can be made between matching performance and characteristics of face images at the visible and near infrared (NIR) spectrums. The Contrast Limited Adaptive Histogram Equalization (CLAHE) technique was used to preprocess images prior to using a commercial matcher.
