Human Tracking System
First Claim
Patent Images
1. A method for tracking a user, the method comprising:
- receiving a depth image;
generating a grid of voxels based on the depth image;
removing a background included in the grid of voxels to isolate one or more voxels associated with a 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.

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.

9. A computer-readable storage medium having stored thereon computer executable instructions for tracking a user, the computer executable instructions comprising instructions for:
-
receiving a depth image comprising pixels; downsampling the pixels in received depth image to generate one or more voxels; isolating one or more voxels associated with a 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. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for tracking a model associated with a user, the system comprising:
-
a capture device, wherein the capture device comprises a camera component that receives a depth image of a scene; and a computing device in operative communication with the capture device, wherein the computing device comprises a processor that generates a downsampled depth image based on one or more pixels in the depth image received from the capture device;
removes a background of the downsampled depth image to isolate a human target;
determines a location or position of one or more extremities of the isolated human target; and
adjusts a model based on the location or position of the one or more extremities. - View Dependent Claims (17, 18, 19, 20)
