GEOSTAT Research team

Geometry and Statistics in acquisition data

Team presentation

GeoStat projecting makes fundamental and applied research on new non linear methods for the analysis of complex signals and systems, using paradigms and tools coming from the notions of scale invariance, predictibility, and the development of new formalisms such as the Multiscale Microcanonical Formalism.

Research themes

GeoStat's research thematics are centered on the following theoretical developments :
  • Multiscale methods developped in Physics for the analysis of complex systems (computation of singularity exponents, Lyapunov exponents and large deviations, various definitions of entropy etc.),
  • Predictibility in complex systems,
  • Optimal wavelet decomposition,
  • Analysis, classification, detection,
and the following applied objectives:
  • Analysis of complex and turbulent signals in earth observation and remote sensing,
  • Digital implementation of adaptative optics in astronomy,
  • Speech analysis.
