Abstract: Various implementations disclosed herein include devices, systems, and methods that use event camera data to track deformable objects such as faces, hands, and other body parts. One exemplary implementation involves receiving a stream of pixel events output by an event camera. The device tracks the deformable object using this data. Various implementations do so by generating a dynamic representation of the object and modifying the dynamic representation of the object in response to obtaining additional pixel events output by the event camera. In some implementations, generating the dynamic representation of the object involves identifying features disposed on the deformable surface of the object using the stream of pixel events. The features are determined by identifying patterns of pixel events. As new event stream data is received, the patterns of pixel events are recognized in the new data and used to modify the dynamic representation of the object.

Abstract: The present embodiments relate to localizing a mobile device in a complex, three-dimensional scene. By way of introduction, the present embodiments described below include apparatuses and methods for using multiple, independent pose estimations to increase the accuracy of a single, resulting pose estimation. The present embodiments increase the amount of input data by windowing a single depth image, using multiple depth images from the same sensor, and/or using multiple depth image from different sensors. The resulting pose estimation uses the input data with a multi- window model, a multi-shot model, a multi-sensor model, or a combination thereof to accurately estimate the pose of a mobile device.

Abstract: Systems, methods, and computer-readable storage media for constructing and using a model for tracking an object are disclosed. The model may be constructed from a plurality of images and a coordinate system defined with respect to the pedestal upon which the object is placed, where the plurality of images correspond to images of the object while the object is placed on a pedestal, and where the pedestal includes a plurality of markers. The model for tracking the object may be configured to provide information representative of a camera position during tracking of the object using a camera. Tracking the object using the model may include obtaining one or more images of the object using a camera, and determining a position of the camera relative to the object based on the model.
