Abstract: A depth image of a scene may be received, observed, or captured by a device. The depth image may then be analyzed to determine whether the depth image includes noise. For example, the depth image may include one or more holes having one or more empty pixels or pixels without a depth value. Depth values for the one or more empty pixels may be estimated and a depth image that includes the estimated depth values for the one or empty more pixels may be rendered.

Abstract: A depth image of a scene may be received, observed, or captured by a device. The depth image may then be analyzed to determine whether the depth image includes a human target. For example, the depth image may include one or more targets including a human target and non-human targets. Each of the targets may be flood filled and compared to a pattern to determine whether the target may be a human target. If one or more of the targets in the depth image includes a human target, the human target may be scanned. A skeletal model of the human target may then be generated based on the scan.
