Classification with Scattering Invariants Signal classification requires to reduce variability with invariant representations, which are stable to deformations and retain enough information for disrimination.Canonical invariants, Fourier or wavelet transforms do not satisfy these properties. Scattering operators iteratively apply wavelet transforms and modulus operators that removes the phase. They build a representation over a path space, which is proved to be invariant to translations and stable to deformations. It characterizes the geometric distribution of image structures. Scattering operators also provide representations of stationary processes, including high order moments which discriminate processes having same Fourier spectrum. Image classification results are shown on data bases of structured patterns and textures.
