    摘要: Disclosed are various embodiments of three-dimensional (3D) video coding using scalable video coding (SVC) spatial scalability. In one embodiment, 3D video is encoded to generate a SVC base layer that includes a left first-resolution view and a right first-resolution view packed in a first frame. 3D video is encoded to generate a SVC enhancement layer that includes a left second-resolution view and a right second-resolution view packed in a second frame. The left second-resolution view and the right second-resolution view may have a higher spatial resolution than the left first-resolution view and the right first-resolution view.

    摘要: Methods and systems for hierarchically layered adaptive median motion vector smoothing are disclosed. Aspects of one method may include generating motion vectors (MVs) for video pictures at each level of a hierarchical motion estimation process, where each level may use different resolution video pictures. The MVs may be smooth filtered at each level to reduce or remove spurious MVs. The smooth filtering may comprise scalar median filtering and/or vector median filtering. The smooth filtering may receive as inputs a plurality of MVs, for example, the MV being filtered and eight MVs from the surrounding video blocks. The vector costs of the nine MVs may be compared to a threshold vector cost, and those MVs with costs above the threshold value may be discarded. The threshold value may be dynamically changed based on, for example, content of the video pictures and/or to adjust a window size of the smoothing filter.

    摘要: Aspects of a method and system for hierarchical motion estimation with multi-layer sub-pixel accuracy and motion vector smoothing are presented. Aspects of the system may include hierarchical motion vector computation that enables motion vectors to be computed at each level in the hierarchy based on a distinct pixel resolution level. A smoothing algorithm may be utilized to suppress spurious motion vector generation. The motion vectors computed at one level in the hierarchy may be utilized when computing motion vectors in a subsequent level. A bias value may be computed for each motion vector that provides an evaluation metric that may enable determination of whether the computed motion vector is to be utilized to enable generation of the interpolated image frame.

    摘要: A 3-dimensional (3D) video transmitter may be operable to encode a 3D video to generate a scalable video coding (SVC) base layer and a SVC enhancement layer. A first view such as a first high-resolution view and a second view such as a second high-resolution view of the 3D video in the SVC enhancement layer may be separate frames. A first half-resolution view and a second half-resolution view of the 3D video in the SVC base layer may be packed in a single frame. The first half-resolution view in the SVC base layer may be a base-layer reference for the first high-resolution view in the SVC enhancement layer for inter-layer prediction of spatial scalable coding. The first high-resolution view in the SVC enhancement layer may be an intra-layer reference for the second high-resolution view in the SVC enhancement layer for intra-layer prediction of temporal scalable coding.
