    generating a plurality of voxels based on a downsampling of the depth image, including generating a first voxel of the plurality of voxels based on at least one pixel that corresponds to background independent of at least one pixel that corresponds to a human target, the first voxel overlapping another voxel in the plurality of voxels;

    removing a background included in the plurality of voxels to isolate one or more voxels associated with the human target;

    determining a location or position of one or more extremities of the isolated human target; and

    adjusting a model based on the location or position of the one or more extremities.
