    摘要: A method and apparatus to enhance the quality of interpolated video, constructed from decompressed video data, comprising denoising the interpolated video data, is described. A low pass filter is used to filter the interpolated video data. In one embodiment, the level of filtering of the low pass filter is determined based on a boundary strength value determined for the interpolated video data and neighboring video data (interpolated and/or non-interpolated). In one aspect of this embodiment, the boundary strength is determined based on proximity of reference video data for the interpolated video data and the neighboring video data.

    摘要: Video analytics systems and methods are described that typically comprise a video encoder operable to generate macroblock video analytics metadata (VAMD) from a video frame. Functional modules receive the VAMD and an encoded version of the video frame is configured to generate video analytics information related to the frame using the VAMD and the encoded video frame. The downstream decoder can use the VAMD to obtain a global motion vector related to the frame, detect and track motion of an object within the frame and monitor a line provided or found within the frame. Traversals of the line by a moving object can be detected and counted using information in the VAMD and the line may be part of a polygon that delineates an area to be monitored within the encoded frame. The VAMD can comprise macroblock level and video frame level information.

    摘要: A method for creating an interpolated video frame using a current video frame, and a plurality of previous video frames is presented. The method includes creating a set of extrapolated motion vectors from at least one reference video frame in the plurality of previous video frames; performing an adaptive motion estimation using the extrapolated motion vectors and a class type of each extrapolated motion vector; deciding on a motion compensated interpolation mode; and, creating a set of motion compensated motion vectors based on the motion compensated interpolation mode decision. An apparatus for performing the method is also disclosed.

    摘要: In general, this disclosure describes encoding and decoding techniques that facilitate more accurate interpolation of skipped video frames. In particular, techniques are described for obtaining motion information that indicates motion for skipped video frames based on translational motion and at least one other motion parameter and applying the motion information to interpolate the skipped video frames. The motion information may, for example, indicate motion based on a motion model that models three or more motion parameters as opposed to conventional two parameter translational motion vectors. The more accurate motion information may either be generated within the decoder performing the interpolation or be transmitted by an encoder in one or more frames. Either way, the techniques reduce the amount of visual artifacts in the interpolated frame.

    摘要: A method and apparatus to process erroneous bi-directionally predicted multimedia data is described. The method includes determining temporal prediction data for the erroneous multimedia data, and estimating the erroneous multimedia data based on the determined temporal prediction data. The temporal prediction data includes data that was used to predict a forward reference section and/or a backward reference section. In some aspects, the temporal prediction data comprises motion vector data of the reference frames which is scaled to correspond to a frame containing the erroneous data.
