The project is funded by the Engineering and Physical Sciences Research Council (EPSRC) and lasts for 2 years. This project will investigate 4D techniques and a computational model for home-based therapy using a depth sensor. This framework envisions developing easy to use facial palsy therapy technologies, which can provide real-time feedback assessing treatment responses of patients. The methods developed for capturing refined 4D geometric models from depth data will open up many new research avenues for real-time application. It will enable 4D facial movement optimisation with the actual geometric data of the underlying facial features of the person.
