20130113877DETERMINING FEATURE VECTORS FOR VIDEO VOLUMES - A volume identification system identifies a set of unlabeled spatio-temporal volumes within each of a set of videos, each volume representing a distinct object or action. The volume identification system further determines, for each of the videos, a set of volume-level features characterizing the volume as a whole. In one embodiment, the features are based on a codebook and describe the temporal and spatial relationships of different codebook entries of the volume. The volume identification system uses the volume-level features, in conjunction with existing labels assigned to the videos as a whole, to label with high confidence some subset of the identified volumes, e.g., by employing consistency learning or training and application of weak volume classifiers.05-09-2013
20130127987SIGNALING DEPTH RANGES FOR THREE-DIMENSIONAL VIDEO CODING - In one example, a video coder, such as a video encoder or a video decoder, is configured to code a first set of one or more depth range values for a first set of video data, wherein the first set of one or more depth range values have respective first precisions, code a second set of one or more depth range values for a second set of video data, wherein the second set of one or more depth range values have respective second precisions different than the respective first precisions, and code at least a portion of the second set of video data using the second set of one or more depth range values. In this manner, the video coder may update precisions (e.g., numbers of bits) used to represent depth range values for coding multiview plus depth video data.05-23-2013
20130141528STEREOSCOPIC VIDEO TEMPORAL FRAME OFFSET MEASUREMENT - A stereoscopic video temporal frame offset measurement system uses an improved signature curve generator to generate a robust signature curve for each of the left and right image sequences of a stereo video signal. The resulting signature curves are cross-correlated over a specified correlation range to generate cross-correlation coefficients. The cross-correlation coefficients are compared to a high threshold, and a temporal frame offset is generated and displayed for each cross-correlation coefficient that exceeds the high threshold. Each new temporal frame offset result is highlighted when displayed, otherwise the last result is displayed in a background fashion.06-06-2013
20110273530BROADCAST RECEIVER AND 3D VIDEO DATA PROCESSING METHOD - A broadcast receiver and a 3D video data processing method are disclosed. A three dimensional (3D) video data processing method for use in a broadcast receiver includes receiving a broadcast signal including three dimensional (3D) video data, extracting display condition information of the 3D video data from the broadcast signal, and controlling an output of the 3D video data using the extracted display condition information.11-10-2011
20110273529CODING OF DEPTH MAPS - Various implementations are described. Several implementations relate to filtering of depth maps. According to a general aspect, a first depth picture is accessed that corresponds to a first video picture. For a given portion of the first depth picture, a co-located video portion of the first video picture is determined. A video motion vector is accessed that indicates motion of the co-located video portion of the first video picture with respect to a second video picture. A second depth picture is accessed that corresponds to the second video picture. A depth portion of the second depth picture is determined, from the given portion of the first depth picture, based on the video motion vector. The given portion of the first depth picture is updated based on the depth portion of the second depth picture.11-10-2011
20110228046SYSTEM AND METHOD FOR FACILITATING CONFIGURATION OF A CONTROLLING DEVICE VIA A 3D SYNC SIGNAL - A controlling device is configures to control functional operations of an appliance by using a 3D sync signal transmitted to synchronize a wearable 3D viewing apparatus with a device adapted to render 3D media to select from a library of command codes a command code set appropriate for controlling functional operations of the appliance. The command codes within the command code set selected from the library of command codes are assigned to respective keys of the controlling device whereupon a subsequent activation of one or more of the respective keys of the controlling device will cause the controlling device to issue a command transmission via use of one or more of the command codes within the command code set selected from the library of command codes to thereby control one or more functional operations of the appliance.09-22-2011

The method for warping a video, comprising steps of (a) receiving a video having at least a frame having a specific area; (b) defining a target video cube having a predetermined warping ratio and including the specific area; and (c) warping the frame so that the warped frame conforms to an aspect ratio of the target video cube.11-17-2011
20110310220DEPTH CAMERA ILLUMINATOR WITH SUPERLUMINESCENT LIGHT-EMITTING DIODE - A depth camera illuminator with a superluminescent light-emitting diode (SLED) in a motion tracking system. One or more SLEDs have a sufficient power, such as 75-200 milliwatts, to extend in a field of view in an area such as a room in a home. To correct for chromatic aberration which would otherwise exist due to the wider range of wavelengths which are emitted by an SLED compared to a laser, an achromatic diffractive optical element is used to disperse the light over the field of view. The achromatic diffractive optical element can have a stepped multi-level profile with three or more levels, or a continuous profile. Based on a tracked movement of a human target, an input is provided to an application in a motion tracking system, and the application performs a corresponding action such as updating a position of an on-screen avatar.12-22-2011
