Human body pose estimation
First Claim
Patent Images
1. A method for determining a position of a body using a set of one or more segments, each segment being associated with a portion of the body, the method comprising:
- identifying a set of one or more pixels in a depth map that includes at least part of the body, the depth map being captured with a depth camera;
for each pixel in the set of pixels, assigning to the pixel a first probability that the pixel is within each segment in the set of segments; and
using the assigned first probabilities to determine a centroid pixel within each of the segments.

Abstract
Techniques for human body pose estimation are disclosed herein. Depth map images from a depth camera may be processed to calculate a probability that each pixel of the depth map is associated with one or more segments or body parts of a body. Body parts may then be constructed of the pixels and processed to define joints or nodes of those body parts. The nodes or joints may be provided to a system which may construct a model of the body from the various nodes or joints.

8. A system for determining a position of a body using a set of one or more segments, each segment being associated with a portion of the body, the system comprising:
-
a processor; and a memory communicatively coupled to the processor when the system is operational, the memory bearing processor-executable instructions that, when executed on the processor, cause the system to at least; identify a set of one or more pixels in the depth map that includes at least part of the body, the depth map being captured with a depth camera; for each pixel in the set of pixels, assign to the pixel a first probability that the pixel is within each segment in the set of segments; and use the assigned first probabilities to determine a centroid pixel within each of the segments. - View Dependent Claims (9, 10, 11, 12, 13)

14. A computer readable storage device having recorded thereon computer executable instructions for determining a position of a body using a set of one or more segments, each segment being associated with a portion of the body, the instructions comprising:
-
identifying a set of one or more pixels in a depth map that includes at least part of the body; for each pixel in the set of pixels, assigning to the pixel a first probability that the pixel is within each segment in the set of segments; and using the assigned first probabilities to determine a centroid pixel within each of the segments. - View Dependent Claims (15, 16, 17, 18, 19)
