Abstract: Techniques related to depth image enhancement for hardware generated depth images are discussed. Such techniques may include determining a depth image enhancement indicator for a depth image based on the depth image and a depth image model and generating pixel depth values for missing pixel depth values of the depth image when the depth image enhancement indicator indicates enhancement. The pixel depth values may be generated based on search windows that extend from a position greater than a predetermined disparity position to a maximum disparity position.

Abstract: Embodiments relate to tracking a pose of a 3D object. In embodiments, a 3D computer model, consisting of geometry and joints, matching the 3D real-world object may be used for the tracking process. Processing the 3D model may be done using collision constraints generated from interpenetrating geometry detected in the 3D model, and by angular motion constraints generated by the joints describing the connections between pieces/segments/bones of the model. The depth data in its 3D (point cloud) form, supplied by a depth camera, may be used to create additional constraints on the surface of the 3D model thus limiting its motion. Combined together, all the constraints, using linear equation processing, may be satisfied to determine a plausible pose of the 3D model that matches the real-world pose of the object in front of the 3D camera.

Abstract: In embodiments, apparatuses, methods and storage media for human-computer interaction are described. In embodiments, an apparatus may include one or more light sources and a camera. Through capture of images by the camera, the computing device may detect positions of objects of a user, within a three-dimensional (3-D) interaction region within which to track positions of the objects of the user. The apparatus may utilize multiple light sources, which may be disposed at different distances to the display and may illuminate the objects in a direction other than the image capture direction. The apparatus may selectively illuminate individual light sources to facilitate detection of the objects in the direction toward the display. The camera may also capture images in synchronization with the selective illumination. Other embodiments may be described and claimed.
