Abstract
An image such as a depth image of a scene may be received, observed, or captured by a device. A grid of voxels may then be generated based on the depth image such that the depth image may be downsampled. A model may be adjusted based on a location or position of one or more extremities estimated or determined for a human target in the grid of voxels. The model may also be adjusted based on a default location or position of the model in a default pose such as a T-pose, a DaVinci pose, and/or a natural pose.

-20. (canceled)
A method for tracking a user, comprising:
- receiving a first depth image, the first depth image being captured by a depth camera;
- in response to identifying an estimated location of an extremity of a user in the first depth image, positioning a part of a model to correspond to the estimated location of the extremity in the first depth image;
- and
- in response to determining that a location of an extremity has not been estimated, adjusting the part of the model to correspond to a portion of the depth image that is located close to the part of the model.
A system, comprising:
- at least one processor;
- and
- computing memory communicatively coupled to the at least one processor, the computing memory comprising executable instructions that upon execution cause the system to perform operations comprising:
- receiving a first depth image, the first depth image being captured by a depth camera;
- identifying an estimated location or position of a first extremity of the user in the first depth image;
- positioning a first part of a model to correspond to the estimated location or position of the first extremity in the first depth image;
- and
- in response to determining that a location or position of a second extremity has not been estimated, adjusting a second part of the model to correspond to a portion of the depth image that is located close to the second part of the model.
A method for tracking a user, comprising:
- receiving a first depth image, the first depth image being captured by a depth camera;
- in response to identifying an estimated location of an extremity of a user in the first depth image, positioning a part of a model to correspond to the estimated location of the extremity in the first depth image;
- and
- in response to determining a failure to estimate a location of an extremity, adjusting the part of the model to correspond to a portion of the depth image that is located close to the part of the model.
