    Abstract: A method of providing a set of feature descriptors configured to be used in matching an object in an image of a camera is provided. The method includes: a) providing at least two images of a first object; b) extracting in at least two of the images at least one feature from the respective image, c) providing at least one descriptor for an extracted feature, and storing the descriptors; d) matching descriptors in the first set of descriptors; e) computing a score parameter based on the result of the matching process; f) selecting at least one descriptor based on its score parameter; g) adding the selected descriptor(s) to a second set of descriptors; and h) updating the score parameter of descriptors in the first set based on a selection process and to the result of the matching process.

    Abstract: Various implementations record a shared event by generating a temporal-based three-dimensional (3D) representation for use in providing/rendering views of the recorded event. For example, a method may include determining that a second device is currently at an event at a physical environment. The method may further include providing a notification to the second device for an option to authorize use of sensor data based on determining that the second device is currently at the event. The method may further include receiving authorization to use the sensor data. The method may further include obtaining the sensor data from the second device in accordance with the authorization. The method may further include generating a temporal-based 3D representation of the event based on the sensor data obtained from the second device and additional sensor data obtained from one or more other devices at the event.

    Abstract: In one implementation, a method includes emitting light with modulating intensity from a plurality of light sources towards an eye of a user. The method includes receiving light intensity data indicative of an intensity of the plurality of glints reflected by the eye of the user in the form of a plurality of glints. The method includes determining an eye tracking characteristic of the user based on the light intensity data. In one implementation, a method includes generating, using an event camera comprising a plurality of light sensors at a plurality of respective locations, a plurality of event messages, each of the plurality of event messages being generated in response to a particular light sensor detecting a change in intensity of light and indicating a particular location of the particular light sensor. The method includes determining an eye tracking characteristic of a user based on the plurality of event messages.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that use external device data to improve user data on a wearable device. For example, an example process may include receiving first sensor data, from a sensor of a wearable electronic device, depicting a user of the wearable electronic device. The process may further include receiving second sensor data depicting the user from a second device separate from the wearable electronic device. At least a part of the user depicted in the second sensor data is absent in the first sensor data. The process may further include determining that a portion of the second sensor data depicts the user based on a similarity between the first sensor data and second sensor data. The process may further include updating a user model based on the second sensor data.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that use light probes to facilitate the display of virtual objects in 3D environments. A light probe provides lighting information that describes light incident on a point in space in a 3D environment. For example, a light probe may describe such incident light using an environment map. Such lighting information can be used to provide realistic appearances for objects placed at or near light probe locations in the 3D environment. Implementations disclosed herein determine the light probe locations in real-time or other 3D environments that are generated based on a live physical environment. A digital representation of the live physical environment is used to determine where to position the light probes, how many light probes to use, and/or various light probe attributes.
