Learned dictionaries for sparse image representation: Properties and results, SPIE 2011

  • Compare MOD, K-SVD, LS-DLA, ODL, RLS-DLA
  • Propose some dictionary properties: mutual coherence, distribution ratio, gap, sparse representation capabilities (SRC), dictionary distance
  • However, not able to find a clear correlation between any property and the performance of the dictionary in an image compression application.
