  This report presents the results of a multi-scale wavelet based scheme for
single image de-hazing and underwater image enhancement. The scheme is fast and
highly localized in addition to global enhancement of hazy images. A PDE-based
formulation enables additional versatility as the iterative nature allows more
flexibility for various types of images. Visual and objective results from
experiments indicate that the proposed approach competes favourably or
surpasses most of the state-of-the-art approaches.
