EXTRACTION OF USER BEHAVIOR FROM DEPTH IMAGES

摘要

Embodiments described herein use depth images to extract user behavior, wherein each depth image specifies that a plurality of pixels correspond to a user. In certain embodiments, one or more average extremity positions of a user, which can also be referred to as average positions of extremity blobs, are extracted from a depth image. An application is then updated based on the average positions of extremity blobs.

主权项

1. A method for extracting user behavior from a depth image that includes a plurality of pixels that correspond to a user, the method comprising:
identifying a pixel of the depth image that corresponds to an extremity of the user; identifying an extremity blob that comprises pixels of the depth image that correspond to the user and are within a specified distance of the pixel identified as corresponding to the extremity of the user; identifying an average position of the extremity blob by determining an average position of the pixels included in the extremity blob; and using the average position of the extremity blob to update an application.
