Analysis of Multiscale Wavelet-based Fractional Gradient-Anisotropic Diffusion Fusion for single hazy and underwater image enhancement
This work addresses image enhancement for hazy and underwater conditions, which is an incremental improvement over existing methods.
The researchers tackled the problem of enhancing single hazy and underwater images using a multi-scale wavelet-based scheme, achieving results that compete favorably or surpass most state-of-the-art approaches in visual and objective metrics.
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.
