You will no longer have to content yourself with merely dressing as Miku on casual Fridays. Researchers at Keio University developed a system that tracks a user's facial expressions and projects them in real time onto the face of a computer-generated avatar:
To detect and track faces, this system uses time-series signal processing. It tracks characteristic points, including the eyes, nose, and mouth, at high speed with high precision. The white dots on the screen show the points used to track the face, and the red line shows the orientation of the face. So you can see that the system is detecting the face appropriately, in line with the way it's facing and the movement of the mouth.
