Abstract: Method and apparatus for deriving a motion vector at a video decoder. A block-based motion vector may be produced at the video decoder by utilizing motion estimation among available pixels relative to blocks in one or more reference frames. The available pixels could be, for example, spatially neighboring blocks in the sequential scan coding order of a current frame, blocks in a previously decoded frame, or blocks in a downsampled frame in a lower pyramid when layered coding has been used.

Abstract: Systems, apparatus and methods are described including determining a prediction residual for a channel of video data; and determining, using the first channel's prediction residual, a prediction residual for a second channel of the video data. Further, a prediction residual for a third channel of the video data may be determined using the second channel's prediction residual.

Abstract: Techniques related to object detection using directional filtering are discussed. Such techniques may include determining directional weighted averages for pixels of an input image, generating a feature representation of the input image based on the directional weighted averages, and performing object detection by applying a multi-stage cascade classifier to the feature representation.

Abstract: Systems, apparatuses and methods may provide for technology to improve an appearance of objects that enter a viewable area of a 360-degree video. The technology may include a head mounted display (HMD), a viewport comprising a viewable area within the HMD, and a memory to store objects of interest not currently in the viewable area.

Abstract: Techniques to identify one or more candidate reference blocks used to generate a prediction block to encode a current coding block. The candidate reference blocks can be in the same layer as the current coding block or a different layer. In addition, the candidate reference blocks do not have to be co-located with the current coding block. Motion vectors and shift vectors can be used to identify the one or more candidate reference blocks. In addition, uniform and non-uniform weighting can be applied to the one or more candidate reference blocks to generate the prediction block. Accordingly, an encoder can determine and identify reference blocks to a decoder that can provide desirable rate-distortion cost.
