Given an image with multiple people, our goal is to directly regress the pose and shape of all the people as well as their relative depth.
... First ... develop a novel method to infer the poses and depth of multiple people in a single image.
... method, called BEV, adds an additional imaginary Bird's-Eye-View representation to explicitly reason about depth.
BEV reasons simultaneously about body centers in the image and in depth and, by combing these, estimates 3D body position.
... exploit a 3D body model space that lets BEV infer shapes from infants to adults.
... BEV outperforms existing methods on depth reasoning, child shape estimation, and robustness to occlusion. ...
