OpenCV: Computer Vision Projects with Python

Modifying the application

Let's look at two approaches to integrating face tracking and swapping into Cameo. The first approach uses a single camera feed and swaps face rectangles found within this camera feed. The second approach uses two camera feeds and copies face rectangles from one camera feed to the other.

For now, we will limit ourselves to manipulating faces as a whole and not subelements such as eyes. However, you could modify the code to swap only eyes, for example. If you try this, be careful to check that the relevant subrectangles of the face are not None.

Swapping faces in one camera feed

For the single-camera version, the modifications are quite straightforward. On initialization of Cameo, we create a FaceTracker and a Boolean variable ...
