Examples are disclosed herein that relate to determining a pose of a handheld object. One example provides a computing system configured to determine a pose of a handheld object comprising a plurality of light sources by acquiring image data of a surrounding environment, detecting a subset of light sources of the plurality of light sources of the handheld object in the image data, and performing a search, without using previous pose data, to determine the pose of the handheld object relative to the computing system. The computing system is further configured to use the pose determined to perform a later search for an updated pose of the handheld object, and if the later search fails to find the updated pose, determine the updated pose by again performing the search without using previous pose data.

Determining a pose of a handheld object

The technology disclosed herein provides various embodiments for mapping glints that reflect off from an object to light sources responsible for the glints. Embodiments disclosed herein are able to correctly map glints to light sources by capturing just a few images with a camera. Each image is captured while illuminating the object with a different pattern of light sources. A glint free image may also be determined. A glint free image is one in which the glints have been removed by image processing techniques.

Mapping glints to light sources

Embodiments are configured to provide video conferencing functionality including using region of interest (ROI) features to provide a video signal, but the embodiments are not so limited. In an embodiment, components of a video conferencing system can operate to provide a video signal using pixel data associated with a ROI. In one embodiment, a video conference device can include a detector that can be used to detect human flesh tone regions in a video scene as part of providing a video stream to one or more conference participants.
