Human shape recovery can in general be categorized in two classes: top-down vs. bottom-up. The former estimates poses by deforming a pre-defined 3D humanoid template non-rigidly frame by frame and avoids unreasonable poses by enforcing constraints on surface deformations. The latter starts with the detected 2D body parts or skeletons, then back-projects the points into 3D space either via depth data or triangulating multiple views. While the top-down scenario has been widely covered and applied in multiple view studios, e.g., Kinovis, the bottom-up approach is less studied and discussed.

In this project, we aim at advancing the bottom-up approach. Specifically, one first recovers rough 3D skeletal poses with state-of-the-art bottom-up approach as initialization, and deform pre-defined human surfaces to fit to those poses. The generic human surface has to be adapted according to the size/scale of the skeleton, so as to yield correct anthropometric measurements (height, length of arms and circumference of waists, etc), as depeicted in the left figure. Skeleton-based animation such as linear-blend skinning, dual-quaternion-blend skinning is also worthwhile a look.

Furthermore, besides relying on skeletal poses, we would also like to investigate the possibility of adjusting/refining human shapes according to the pressure measurements, as shown in the right figure.
