CONVOLT: CONVolutional Operator Learning Toolbox

The CONVolutional Operator Learning Toolbox (CONVOLT) – for Matlab – contains various fast and convergent algorithms that can train sparsifying filters associated with convolutional regularizers from large datasets.

Subdirectories (in alphabetical order):

  • CAOL algorithms for convolutional analysis operator learning (CAOL)
  • CDL algorithms for convolutional dictionary learning (CDL)
  • dataset datasets: Fruit, City
  • image_helpers preprocessing toolbox
