Lei Hang, Kohei Inoue, Kiichi Urahama · 2015
We propose a unified method for enhancing color images photographed under bad conditions, such as foggy, ill-exposed and underwater photographs.Input images are firstly enhanced by hue-preserving unsharp masking and next their color is changed by a cross white balance procedure.The hue of colors is almost preserved for foggy and ill-exposed images while colors are changed for underwater photographs.
