    • Implementations of the teachings herein include coding video data with an alternate reference frame generated using a temporal filter. The alternate reference frame is generated by determining a first weighting factor, for each corresponding block of a respective frame of a filter set, that represents a temporal correlation of the block with the corresponding block, determining a second weighting factor, for each pixel for each corresponding block of the respective frame of the filter set, that represents a temporal correlation of the pixel to a spatially-correspondent pixel in the block, determining a filter weight for each pixel in the block and for each spatially-correspondent pixel is each corresponding block based on the first weighting factor and the second weighting factor, and generating a weighted average pixel value for each pixel position in the block to form a block of the alternate reference frame based on the filter weights.
    • 这里的教导的实现包括使用时间滤波器生成的替代参考帧对视频数据进行编码。 通过为滤波器组的相应帧的每个相应块确定第一加权因子来生成替代参考帧,该第一加权因子表示该块与相应块的时间相关性,为每个像素确定每个像素的第二加权因子 滤波器组的相应帧的相应块,其表示像素与块中的空间相应像素的时间相关性,确定块中每个像素和每个空间相应像素的滤波器权重分别是对应块 基于第一加权因子和第二加权因子,并且为块中的每个像素位置生成加权平均像素值,以基于滤波器权重形成替代参考帧的块。

    • A method and apparatus for performing implicit video location augmentation are provided. Implicit video location augmentation may include identifying a first geolocation for a first frame from a plurality of video frames based on a first image captured by the first frame, identifying a second geolocation for a second frame from the plurality of video frames based on a second image captured by the second frame, determining, by a processor, a third geolocation for a third frame from the plurality of video frames based on the first geolocation and the second geolocation, and storing an updated plurality of video frames such that the first frame is associated with the first geolocation, the second frame is associated with the second geolocation, and the third frame is associated with the third geolocation.
    • 提供了用于执行隐式视频位置增加的方法和装置。 隐式视频位置增加可以包括基于由第一帧捕获的第一图像来识别来自多个视频帧的第一帧的第一地理位置,基于第二图像识别来自多个视频帧的第二帧的第二地理位置 由第二帧捕获,由处理器基于第一地理位置和第二地理定位从多个视频帧中确定第三帧的第三地理位置,并存储更新的多个视频帧,使得第一帧相关联 在第一地理定位中,第二帧与第二地理位置相关联,并且第三帧与第三地理位置相关联。
