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 background included in the grid of voxels may also be removed to isolate one or more voxels associated with a foreground object such as a human target. A location or position of one or more extremities of the isolated human target may then be determined.

(canceled)
A computer-implemented method for determining an orientation of one or more extremities comprising:
- generating a grid of voxels based on a depth image;
- isolating one or more voxels associated with a human target;
- generating an extremity volume based on a displacement based on locations or positions of a head and a center of the human target;
- and
- determining orientations of one or more extremities within the extremity volume.
A system comprising a processor and memory, the memory storing computer-executable instructions that, when executed by the processor, cause the system to perform operations comprising:
- generating a grid of voxels based on a depth image;
- isolating one or more voxels associated with a human target;
- generating an extremity volume based on a displacement based on locations or positions of a head and a center of the human target;
- and
- determining orientations of one or more extremities within the extremity volume.
A computer-readable storage medium storing computer-executable instructions that, when executed by a processor of a computing device, cause the computing device to perform operations comprising:
- generating a grid of voxels based on a depth image;
- isolating one or more voxels associated with a human target;
- generating an extremity volume based on a displacement based on locations or positions of a head and a center of the human target;
- and
- determining orientations of one or more extremities within the extremity volume.
