Abstract: Highlights•Mostly, regularization-based methods do not constrain the transmission map, which degrades the quality of the resultant image.•A robust regularization scheme is proposed that constraints the transmission map during its enhancement.•A nonconvex energy function is constructed that leverages the mutual structural information of the guidance and transmission map.•The nonconvex problem is solved by a majorize-minimization algorithm
