1. On a computing system, a method comprising:
- receiving a depth video;
receiving a light intensity video at least partially spatially-registered to the depth video;
finding a candidate human head in the depth video using a head detector;
spatially resolving a head region of the light intensity video with a three-dimensional location of the candidate human head in the depth video, the head region defining a limited portion of the light intensity video; and
performing facial recognition on only the head region of the light intensity video using a face recognizer.

Abstract
A candidate human head is found in depth video using a head detector. A head region of light intensity video is spatially resolved with a three-dimensional location of the candidate human head in the depth video. Facial recognition is performed on the head region of the light intensity video using a face recognizer.

9. A computing system, comprising:
-
a logic machine; and a storage machine holding instruction executable by the logic machine to; receive a depth video; receive an infrared video at least partially spatially-registered to the depth video; find a candidate human head in the depth video using a previously-trained, machine-learning head detector; spatially resolve a head region of the infrared video with a three-dimensional location of the candidate human head in the depth video, the head region defining a limited portion of the infrared video; perform facial recognition on only the head region of the infrared video using a previously-trained, machine-learning face recognizer; and perform skeletal modeling on a body region of the depth video using a previously-trained, machine-learning body tracker to produce a skeletal model, the body region being spatially contiguous with the three-dimensional location of the candidate human head, and the body region defining a limited portion of the depth video. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A computing system, comprising:
-
a logic machine; and a storage machine holding instruction executable by the logic machine to; receive a depth video; receive an infrared video at least partially spatially-registered to the depth video; find a candidate human head in the depth video using a previously-trained, machine-learning head detector; spatially resolve a head region of the infrared video with a three-dimensional location of the candidate human head in the depth video, the head region defining a limited portion of the infrared video; perform facial recognition on only the head region of the infrared video using a previously-trained, machine-learning face recognizer; perform skeletal modeling on a body region of the depth video using a previously-trained, machine-learning body tracker to produce a skeletal model, the previously-trained, machine-learning body tracker being configured to constrain a head joint of the skeletal model to the three-dimensional location of the candidate human head as identified by the previously-trained, machine-learning head detector, the body region being spatially contiguous with the three-dimensional location of the candidate human head, and the body region defining a limited portion of the depth video. - View Dependent Claims (17, 18, 19, 20)
