Wavelets to reconstruct turbulence multifractals from experimental image sequences

Abstract : In the context of turbulent fluid motion measurement from image sequences, we propose in this paper to reverse the traditional point of view of wavelets perceived as an analyzing tool: wavelets and their properties are now considered as prior regularization models for the motion estimation problem, in order to exhibit some well-known turbulence regularities and multifractal behaviors on the reconstructed motion field.
