1. An apparatus, comprising:
one or more processors configured to:
obtain an image of a person;
determine, based on one or more machine-learned (ML) models, respective angles of a first plurality of joints of the person based on the image of the person, wherein the first plurality of joints is associated with a root kinematic chain that includes a chest area or a pelvis area of the person, wherein the respective angles of the first plurality of joints include positional information about the first plurality of joints, and wherein the respective angles of the first plurality of joints and the positional information about the first plurality of joints indicate a position of the person as depicted in the image;
determine, based on the one or more ML models, respective angles of a second plurality of joints of the person based on the image of the person and the position of the person, wherein the second plurality of joints is associated with a head kinematic chain that includes a head area of the person or with a limb kinematic chain that includes a limb area of the person, and wherein the respective angles of the second plurality of joints are determined based on a range of joint angle values dictated by the position of the person; and
estimate a human model associated with the person based at least on the respective angles of the first plurality of joints of the person and the respective angles of the second plurality of joints of the person.
