I wonder where I can find a full list of Action Unit names which are detected from Affdex? I have manually identified some: browfurrow (AU4), browraise (AU2), chinraise (AU17). However, an official information document will be a better choice for me. Thanks
We follow the same FACS system for naming the AU's, you can find the list of Action Units on Wikipedia. For a more visual representation you can refer to Academic Pages.
