Assignee: HINGE HEALTH, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A non-transitory medium with instructions stored thereon that, when executed by a processor of a computing system, cause the computing system to perform operations comprising:
obtaining, as input, a two-dimensional (2D) image that includes a person;
determining (i) a 2D joint skeleton of joints included in the 2D image and (ii) a 2D joint heatmap that indicates a 2D location of each of the joints included in the 2D joint skeleton;
applying the 2D joint heatmap to a convolutional neural network that includes at least one three-dimensional (3D) convolutional layer,
wherein depth resolution is expanded by the convolutional neural network to produce an estimated depth for each of the joints; and

combining the estimated depth of each of the joints with the 2D joint skeleton, so as to construct a 3D joint skeleton of the joints included in the 2D image.
