First Claim
Patent Images
1. A method for image processing, comprising:
- receiving a depth image of a scene containing a human subject;
receiving a color image of the scene containing the human subject;
identifying a part of a body of the subject in at least one of the images;
evaluating a quality of both the depth image and the color image, and selecting, responsively to the quality, one of the images to be dominant in processing of the part of the body in the images; and
localizing the identified part in the dominant one of the images, while using supporting data from the other one of the images.

Abstract
A method for image processing includes receiving a depth image of a scene containing a human subject and receiving a color image of the scene containing the human subject. A part of a body of the subject is identified in at least one of the images. A quality of both the depth image and the color image is evaluated, and responsively to the quality, one of the images is selected to be dominant in processing of the part of the body in the images. The identified part is localized in the dominant one of the images, while using supporting data from the other one of the images.

20. Apparatus for image processing, comprising:
-
an input interface coupled to receive a depth image of a scene containing a human subject and to receive a color image of the scene containing the human subject; and a processor, which is configured to identify a part of a body of the subject in at least one of the images, to evaluate a quality of both the depth image and the color image, and to select, responsively to the quality, one of the images to be dominant in processing of the part of the body in the images, and to localize the identified part in the dominant one of the images, while using supporting data from the other one of the images. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

- 39. A computer software product, comprising a non-transitory computer-readable medium in which program instructions are stored, which instructions, when read by a computer, cause the computer to receive a depth image of a scene containing a human subject and to receive a color image of the scene containing the human subject, to identify a part of a body of the subject in at least one of the images, to evaluate a quality of both the depth image and the color image, and to select, responsively to the quality, one of the images to be dominant in processing of the part of the body in the images, and to localize the identified part in the dominant one of the images, while using supporting data from the other one of the images.

58. A method for image processing, comprising:
-
receiving a depth image of a scene containing a human subject; receiving a color image of the scene containing the human subject; identifying a part of a body of the subject in at least one of the images; evaluating a quality of both the depth image and the color image, and selecting, responsively to the quality, one of the images to be dominant in processing of the part of the body in the images; and segmenting the identified part in the dominant one of the images, while using supporting data from the other one of the images.
