Abstract
An image and video enhancement technique is described that allows a core enhancement algorithm to be applied to images captured in various challenging lighting conditions. The technique detects a lighting impairment and inverts the image if it is a low-light impairment. The inverted low-light image is similar to haze impairment images, allowing both haze images and low-light images to be enhanced using the same enhancement algorithm.
