The authors present a new technique for estimating the distance of visibility in fog conditions. They base their technique on a psychovisual model and on contrast estimation with wavelet transform. For this application, they introduce specific B-spline wavelets for good space and frequency localization and for fast implementation. Using images stemming from situations on motorways, they compare their technique to a direct local contrast calculation.
