Embodiment Construction

[0017] The detailed description provided below in connection with the accompanying drawings is intended as a description of the present example and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the example and the sequence of steps for building and operating the example. However, the same or equivalent functions and sequences can be accomplished by different examples.

[0018] figure 1 is a schematic diagram of tracking hand gestures using the image capture device 102 forward, upward, or on the user's 100 shoulder. exist figure 1 In the example shown at the top of , the user 100 is sitting at a table making hand gestures in front of a display screen 104 on which is the image capture device 102 . In this example, an image of the hand is drawn on the display screen 104 based on the 3D hand model and the tracked pose of the user's hand. However, this is only an example and t...

Abstract

The invention relates to tracking hand / body pose. Tracking hand or body pose from image data is described, for example, to control a game system, natural user interface or for augmented reality. In various examples a prediction engine takes a single frame of image data and predicts a distribution over a pose of a hand or body depicted in the image data. In examples, a stochastic optimizer has a pool of candidate poses of the hand or body which it iteratively refines, and samples from the predicted distribution are used to replace some candidate poses in the pool. In some examples a best candidate pose from the pool is selected as the current tracked pose and the selection processes uses a 3D model of the hand or body.

Description

Background technique [0001] Real-time articulated hand tracking from image data has the potential to open new human-machine interaction scenarios. However, the dexterity and degrees of freedom of the human hand make visual tracking of a fully articulated hand more challenging. This also lends itself to real-time articulated body tracking. [0002] Embodiments described herein are not limited to implementations that address any or all of the shortcomings of known hand / body pose trackers. Contents of the invention [0003] The following presents a simplified summary of the disclosure in order to provide the reader with a basic understanding. This summary is not an extensive overview of the disclosure and does not identify key / critical elements or delineate the scope of the specification. Its sole purpose is to present a selection of concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later. [0004] Tracking of han...
