In this paper, an image enhancement algorithm is presented for identification of corrosion areas and dealing with low contrast present in shadow areas of an image.  ...  Then, part of the enhanced image is combined with the original tone component, followed by saturation and conversion to red-green-blue color space to obtain the enhanced corrosion image.  ...  can be effectively carried out by choosing a decomposition level that 4 Shock and Vibration Shock and Vibration keeps the computational complexity low, but at the same time enhances the image details  ...

To obtain a high-quality flow field, we present a novel smoothing scheme for the structure tensor based on Poisson's equation.  ...  The smoothing process regularizes directional image features while the shock filter provides a sharpening effect. Both operations are guided by a flow field derived from the structure tensor.  ...  ] and Weickert's coherence-enhancing shock filter [Wei03] .  ...
