Mission-critical monitoring based on surround suppression variational Retinex enhancement for non-uniform illumination images

Abstract In this letter, a surround suppression variational Retinex enhancement algorithm (SSVR) is proposed for non-uniform illumination images. Instead of a gradient module, a surround suppression mechanism is used to provide spatial information in order to constrain the total variation regulariza...
