To run the experiment on the AR database:

1. Download .mat file of AR, e.g., AR_database and AR_database_Occlusion 
   from http://www4.comp.polyu.edu.hk/~csmyang/Publication.html, then copy
   them to this folder. 

2. Run \demo_RCR_AR.m to get the recognition accuracies on AR without disguise.

3. Run \demo_RCR_AR_disguise.m to get the recognition accuracies on AR with disguise.
