  Image enhancement using the visible (V) and near-infrared (NIR) usually
enhances useful image details. The enhanced images are evaluated by observers
perception, instead of quantitative feature evaluation. Thus, can we say that
these enhanced images using NIR information has better features in comparison
to the computed features in the Red, Green, and Blue color channels directly?
In this work, we present a new method to enhance the visible images using NIR
information via edge-preserving filters, and also investigate which method
performs best from a image features standpoint. We then show that our proposed
enhancement method produces more stable features than the existing
state-of-the-art methods.
