    • A method and apparatus for reduced complexity video and image processing with special chroma handling are disclosed. Frame-type decisions are made on a video stream made up of a sequence of frames. A first subset of the frames are selected to be monochrome and generated without chroma data. A second subset of the frames are selected to be in color and generated with chroma components. In one embodiment, the first subset of frames includes odd frames and the second subset of frames includes even frames in the video stream. Under higher video frame rates, the lack of color in every other frame is not visible to the end viewer. Accordingly, subsequent processing of the output video stream permits luma-only processing of many frames in the video stream, extensively reducing the amount of computation.
    • 公开了一种用于降低复杂度的具有特殊色度处理的视频和图像处理的方法和装置。 在由一系列帧组成的视频流上进行帧型决定。 帧的第一子集被选择为单色并且没有色度数据生成。 帧的第二子集被选择为彩色并由色度分量生成。 在一个实施例中,帧的第一子集包括奇数帧,并且帧的第二子集包括视频流中的偶数帧。 在更高的视频帧速率下,每个其他帧中缺少颜色对于终端观看者是不可见的。 因此,输出视频流的后续处理允许视频流中许多帧的仅亮度处理,从而大大减少了计算量。

    • At least a method and a system are described for providing frame rate upconversion by way of using “short side” or bidirectional interpolation in generating interpolated frames. In a representative embodiment, the method may comprise receiving a first frame of video corresponding to a first frame time and a second frame of the video corresponding to a second frame time, computing a first absolute difference between the first frame time and an interpolated frame time wherein the interpolated frame time temporally is located between the first frame time and the second frame time. The method further comprises using a first motion vector field and the first frame to compute a third frame at the interpolated frame time. The method further comprises outputting the third frame as the interpolated frame at the interpolated frame time if the first absolute difference is less than or equal to a first threshold value.
    • 描述了至少一种方法和系统,用于通过在生成内插帧中使用“短边”或双向插值来提供帧速上变频。 在代表性实施例中,该方法可以包括:接收对应于第一帧时间的第一帧视频和对应于第二帧时间的视频的第二帧,计算第一帧时间和内插帧时间之间的第一绝对差 其中所述内插帧时间在时间​​上位于所述第一帧时间和所述第二帧时间之间。 该方法还包括使用第一运动矢量场和第一帧来在内插帧时间计算第三帧。 该方法还包括:如果第一绝对差小于或等于第一阈值,则以内插帧时间输出第三帧作为内插帧。
