We explore marker-less tracking methods for the purpose of
evaluating the efficacy of facial re-constructive surgery on patients with
facial palsies. After experimenting with several optical flow methods, we
choose an approach that results in less than 2 pixels in tracking error for
15 markers tracked on the face. A novel method is presented that utilizes
the non-rigid deformation observed on facial skin tissue to visualize the
severity of facial paralysis. Results are given on a dataset that contains
three videos of an individual recorded using a standard definition camera
both before and after undergoing facial reconstructive surgery over a
period of three years.
