High-resolution 3D surface strain magnitude using 2D camera and low-resolution depth sensor ?
Measures the 3-D surface strain impacted on the face during facial expressions. Describes an automatic approach for calibrating Kinect with external camera. Method shows high correlation between 3-D strain maps calculated from two views. Method robust to multiple depth resolutions. Over 100 subjects and 600 expressions used for testing.
