  • Abstract In wavelet analysis, the signal reconstruction and statistical estimators are strongly influenced by the wavelet shape that controls the time-frequency localization properties. However, this dependency does not imply that the wavelet form is physically relevant to extract spatially invariant wavelet-based shape signatures. A new statistical estimator is proposed in order to quantify the influence of the wavelet on the spatial detection. This indicator is then used to analyze signals… CONTINUE READING
