Wavelet transform of a bidimensional fractal field [Transformée en ondelettes d'un champ fractal bidimensionnel].

The bidimensional scalar field is visualized as a tridimensional surface. The module of the wavelet transform is color mapped on this surface -the null phase lines are white painted-. Correlations between the field and its transform are then easier to exhibit.
