Abstract:
Implementations include methods and systems for a converting reference images or video to 3D images or video. A two-step conversion is described which accomplishes warping and hole filling on a pixel-by-pixel basis. In one implementation, of a plurality of pixel values of a reference image at a plurality of first collinear pixels locations are successively mapped to a respective plurality of second pixel locations of a destination image. Between two of the mappings, a location of a hole between two of the second pixel locations may be identified and filled.
Abstract:
Aspects of this disclosure relate to a method of coding video data. In an example, the method includes determining a first residual quadtree (RQT) depth at which to apply a first transform to luma information associated with a block of video data, wherein the RQT represents a manner in which transforms are applied to luma information and chroma information. The method also includes determining a second RQT depth at which to apply a second transform to the chroma information associated with the block of video data, wherein the second RQT depth is different than the first RQT depth. The method also includes coding the luma information at the first RQT depth and the chroma information at the second RQT depth.
Abstract:
This disclosure describes techniques for coding 3D video block units. In one example, a video encoder is configured to receive one or more texture components from at least a portion of an image representing a view of three dimensional video data, receive a depth map component for at least the portion of the image, code a block unit indicative of pixels of the one or more texture components for a portion of the image and the depth map component. The coding comprises receiving texture data for a temporal instance of a view of video data, receiving depth data corresponding to the texture data for the temporal instance of the view of video data, and encapsulating the texture data and the depth data in a view component for the temporal instance of the view, such that the texture data and the depth data are encapsulated within a common bitstream.
Abstract:
Packetized video data with a base-layer and at least one enhancement-layer organized in a GOP structure may contain packet loss errors. A method for detecting such errors includes the steps of reading header information relating to a layer, generating a scheme or selecting a predefined scheme according to the header information. The scheme can be made up of a display order number, and/or a number of reference frames and temporal level for the frames of the respective layer. The method can then extract from received video data frames the display order number, and/or the number of reference frames and temporal level parameters, and detect that one or more frames or packets are missing. The received parameters are compared with the parameters of expected frames according to the scheme and a missing packet or frame is determined by a mismatch between received and expected parameters.
Abstract:
This disclosure relates to techniques for constructing a combined reference picture list, List C, based on List 0 and List 1, used for uni-directional prediction of video blocks in any direction. The techniques include coding one or more syntax elements defined to indicate construction information for List C, and performing reference picture list construction for List C from List 0 and List 1 based on the syntax elements. The one or more syntax elements may indicate that List C is used for uni-directional prediction, and may also indicate a number of reference pictures identified in List C and a reference index of a reference picture for each entry in List C. Each coded video block of a B slice may have an associated syntax element, i.e., inter_pred_idc, to indicate whether the video block is bi-predicted from List 0 and List 1 (Bi) or uni-directional predicted from List C (Pred_LC).
Abstract:
A Gilbert mixer (200) comprising four switching transistors (Q3, Q4, Q5, Q6), two intermediate frequency transistors (Q1, Q2), and one or more DC decoupling components (202). The one or more DC decoupling components (202) are coupled between the switching transistors (Q3, Q4, Q5, Q6) and the intermediate frequency transistors (Q1, Q2) in order to DC decouple the switching transistors (Q3, Q4, Q5, Q6) from the intermediate frequency transistors (Q1, Q2).
Abstract:
This disclosure describes techniques for estimating a depth of image objects for a two-dimensional (2D) view of a video presentation. For example, an initial indication of depth (e.g., an optical flow) may be determined for a 2D view. The initial indication of depth may be used to estimate global motion, e.g., motion of an observer (e.g., camera), of the 2D view. The initial indication of depth may be modified based on the estimation of global motion to create a global motion-adjusted indication of depth. The global motion-adjusted depth indication may be used to create a depth map for the 2D view, which may be used to generate an alternative view of the video presentation that may be used to display a three-dimensional (3D) video presentation.
Abstract:
The present invention provides the multifunctional biological and biochemical sensor technology based on the integration of ZnO nanotips with bulk acoustic wave (BAW) devices, particularly, quartz crystal microbalance (QCM) and thin film bulk acoustic wave resonator (TFBAR). ZnO nanotips provide giant effective surface area and strong bonding sites. Furthermore, the controllable wettability of ZnO nanostructured surface dramatically reduces the liquid consumption and enhances the sensitivity of the biosensor device.
