I am currently a researcher at LIP, ENS Lyon, in the project DANTE.

I am working on anisotropic energy optimization for image restoration and segmentation, in particular the well-know Mumford-Shah functional. I'm studying theorical and numerical aspects using Gamma-convergence, proximal algorithms, nonconvex optimization and discrete calculus.

Research topics :

  • Image and signal processing
  • Nonsmooth and nonconvex optimization
  • Proximal algorithms
  • Discrete calculus
  • Numerical shape optimization with Gamma-convergence
  • Restoration result on a color image with noise 0.1.
  • Restoration and segmentation of a color image with noise 0.05.
  • Cartooning example.
