HUMAN TRACKING SYSTEM
First Claim
Patent Images
1. A method for tracking a user, the method comprising:
- receiving a depth image;
generating a first voxel of a plurality of voxels based on at least one pixel of the depth image that corresponds to a 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 the first voxel from 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 based on the one or more voxels associated with the human target; and
adjusting a model based on the location or position of the one or more extremities.

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 be determined and a model may be adjusted based on the location or position of the one or more extremities.
