ToDos

• Test Script:
  • For testing, see python implementation dictionary learnning and image denoising. We still need to create a wrapper to call our C implementation of dictionary learning from above python scripts.
• Complete Implementation:
  • Implementation of LARS (Check FISTA implementation in above matlab implementation). Possibly replace LARS with FISTA as done in the matlab implementation.

Denoising Demonstration

• After compilation, to test denoising.cpp:
  • ./applicationName Lenna256.png Lenna256Noisy.png
