Analyse multifractals des signaux géophysiques
Since twenty years wavelet transform was recognized as a privileged tool for analysis of the fractals objects. We exploited the self-similarity of the wavelet transform to detect singularity which is a fractal signal characterization .In a first part, we use the wavelet transform modulus maxima line...
