Modeling the Human Body in 3D

In the previous chapters, we explored ideas for modeling a 3D scene and the objects in them. Most of the objects we modeled were static and unchanging, but many applications of computer vision in real life center around humans in their natural habitat. We want to model their interactions with other humans and objects in the scene.

There are several applications for this. Snapchat filters, FaceRig, virtual try-on, and motion capture technology in Hollywood all benefit from accurate 3D body modeling. Consider, for example, an automated checkout technology. Here, a retail store is equipped with several depth-sensing cameras. They might want to detect whenever a person retrieves an object and modify their checkout ...
