Sir,First of all I would like to thank you for your kind response. how to give input image here and how to get the action units from it ? I couldn able to understand the code.

run_demo.m gives the only real clue. It appears that the inputs have already been given and pre-processed and converted to a couple of .mat files. No code is provided to do that pre-processing so you would need to figure it out from the paper and by looking at the original version of the data set that they pre-processed.
