Looks like the filters from the notebook are a re-organized view of figure 3 from http://www.cs.toronto.edu/~fritz/absps/imagenet.pdf (as the caffe page cites at the top). I'm not a lawyer, so i don't really know if making a 'new' image using the components of the copyrighted image is derivative or not.

Please do, if this is really legit, it's in your best interest to set it up in the most professional way possible. It'd probably be better to get the organizers of the festival to put the content of the post in one of their pages and you link there.
