20140029836 | STEREOSCOPIC DEPTH RECONSTRUCTION WITH PROBABILISTIC PIXEL CORRESPONDENCE SEARCH - Generally, this disclosure provides devices, systems and methods for stereoscopic depth reconstruction, for 3-D imaging, with improved probabilistic pixel correspondence searching. The method may include obtaining a first image and a second image; down-sampling the first image; down-sampling the second image; generating a reduced resolution disparity matrix for the first down-sampled image including estimated correspondence pixels from the second down-sampled image; generating a reduced resolution quality matrix including quality metric values associated with pixels in the reduced resolution disparity matrix; up-sampling the reduced resolution disparity matrix to a first full resolution disparity matrix; up-sampling the reduced resolution quality matrix to a full resolution quality matrix; and generating a second full resolution disparity matrix for the first image including estimated correspondence pixels from the second image, the estimated correspondence pixels selected from a search range in the second image. | 01-30-2014 |
20150104096 | 3D OBJECT TRACKING - 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. | 04-16-2015 |
20150116214 | GESTURE BASED HUMAN COMPUTER INTERACTION - Apparatus, computer-readable storage medium, and method associated with human computer interaction. In embodiments, a computing device may include a plurality of sensors, including a plurality of light sources and a camera, to create a three dimensional (3-D) interaction region within which to track individual finger positions of a user of the computing device. The light sources and the camera may be complementarily disposed for the camera to capture the finger or hand positions. The computing device may further include a 3-D interaction module configured to analyze the individual finger positions within the 3-D interaction region, the individual finger movements captured by the camera, to detect a gesture based on a result of the analysis, and to execute a user control action corresponding to the gesture detected. Other embodiments may be described and/or claimed. | 04-30-2015 |
20150131852 | OBJECT POSITION DETERMINATION - 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. | 05-14-2015 |
