LAUD is the implementation of our LBP-based AU detector, desribed in this paper. It is developed by me as a standalone, WIN32 command-line version of the AU detector implemented in the SEMAINE project. It comes with trained models for the following AUs: AU1, AU2, AU$, AU5, AU6, AU7, AU9, AU12, AU14, AU15, AU20, AU25, AU27, and AU45. Not all of these are equally good though. AU1, AU2, AU4, AU12, and AU25 were deemed good enough to be used in SEMAINE, but I will let you draw your own conclusions. The system assumes that the image is already frontal. If you pass the -f argument, it will do face detection but not registration. If people are interested, I may integrate a simple in-plane head registration method that we also use in the SEMAINE system.
How to use it: Detect AU 1 in a single image:
LAUD 1 C:\tmp\img0001.png -v -f
or in all images in a directory:
LAUD 1 C:\tmp\imdir\ -v -f -d
Call LAUD without input arguments to see all input options. If you process a whole directory, the results will be stored in that directory.
The BoRMaN programme detects 20 fiducial facial points. Instead of scanning an image or image region for the location of a facial point, it can use every location in a point's neighbourhood to predict where the target point is relative to that location. This considerable speeds up point detection. In only a few iterations the facial point can be found. Markov networks are used to confirm whether a set of predicted facial points adhere to shape statistics, and if they don't the Markov nets suggest new locations to continue the search for the facial point.
