SYSTEMS AND METHODS FOR REMOVING A BACKGROUND OF AN IMAGE
First Claim
Patent Images
1. A computer-readable storage device having stored thereon computer executable instructions for processing depth information of a scene, the computer executable instructions comprising instructions for:
- receiving a depth image of the scene, wherein the depth image comprises one or more objects;
comparing a value associated with voxels in one or more objects in the depth image with a corresponding value of a reference voxel;
identifying voxels as moving when a difference between the value and the corresponding value exceeds a motion threshold; and
identifying other voxels as non-moving.

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 then be discarded to isolate one or more voxels associated with a foreground object such as a human target and the isolated voxels associated with the foreground object may be processed.

8. A system for processing depth information of a scene, the system comprising:
-
a capture device configured to capture a depth image of the scene; and a computing device communicatively coupled to the capture device, wherein the computing device comprises a processor and memory storing thereon computer-readable instructions that, when executed by the processor, cause the computing device to perform operations comprising; receiving a depth image of the scene, wherein the depth image comprises one or more objects; comparing a value associated with voxels in one or more objects in the depth image with a corresponding value of a reference voxel; identifying voxels as moving when a difference between the value and the corresponding value exceeds a motion threshold; and identifying other voxels as non-moving. - View Dependent Claims (9, 10, 11, 12, 13)
