We now have two versions of Cameo. One version tracks faces in a single camera feed and, when faces are found, swaps them by copying and resizing. The other version tracks faces in two camera feeds and, when faces are found in each, copies and resizes faces from one feed to replace faces in the other. Additionally, in both versions, one camera feed is made visible and effects are applied to it.

These versions of Cameo demonstrate the basic functionality that we proposed two chapters ago. The user can displace his or her face onto another body, and the result can be stylized to give it a more unified feel. However, the transplanted faces are still just rectangular cutouts. So far, no effort is made to cut away non-face parts of the rectangle or to align superimposed and underlying components such as eyes. The next chapter examines some more sophisticated techniques for facial blending, particularly using depth vision.
