Abstract
This project pursues automatic facial tic detection in video recordings of Gilles de la Tourette syn-
drome patients. Current diagnostic methods using a severity measurement scales and tic counts require
huge e ort from the therapist and the patient. By automating these diagnostic methods, this would alle-
viate these e orts. A study by Chappell et al. shows that manually counting tics in videotape recordings
is feasible[9]. Only few studies used arti cial intelligence to automate the process of tic detection. A
study by M. Bernabei is the most prominent one and shows that automatic tic detection with triaxial accelerometers is possible[3]. In the current project, distinctive features used by experts have been explored
for their use in a system using computer vision and machine learning techniques. An implementation for
this system is made and the performance is benchmarked. This project explored whether this approach
was feasible and yields recommendations for further improvements. Finally, results and guidelines for
the design of a system that uses automated tic detection for psychotherapeutic feedback and exercises
are given.
