I contribute to the deconvolution algorithms of the scikit-image library.

Packages

  • A Conjugate Gradient descent optimisation function design for quadratic criterion and linear problem defined on large unknown (compatible with complex unknown). Any feedback, patch and issue report are welcome.
  • An unsupervised deconvolution based on the Wiener-Hunt filter. The estimation of the regularisation parameter is done thanks to a Gibbs sampler.

Some extra

  • Several python utility and small tools here
  • Several Matlab functions (related to Fourier transform, optimisation, MCMC and various utility) in this archive

Jupyter notebooks

  • A notebook of PO algorithm illustrated on a Super-Resolution problem
