    • Systems and methods of signaling different filter structures for each pixel or sub-pixel position in motion compensation prediction video coding are provided. An encoder signals to a decoder one filter structure among a plurality of pre-defined candidates that is used for a respective pixel or sub-pixel position. In accordance with one embodiment, filter structures signaled to the decoder from the encoder "switch" between directional filter and radial filter structures during interpolation at the sub-pixel level. In accordance with another embodiment, filter structures that are signaled may switch between a directional filter structure and a separable filter structure at the sub-pixel level. Thus, not only can an encoder switch between different filter structures during interpolation, but a filter structure pair is provided that the encoder can utilize to interpolate a wide range of signals without increasing tap-length.
    • 提供了用于在运动补偿预测视频编码中为每个像素或子像素位置发送不同滤波器结构的系统和方法。 编码器向用于各个像素或子像素位置的多个预定义候选中的一个滤波器结构向解码器发信号。 根据一个实施例,滤波器结构在子像素级的内插期间从编码器向方向滤波器和径向滤波器结构之间的信号转换到解码器。 根据另一个实施例,被信号化的滤波器结构可以在子像素级别处在方向滤波器结构和可分离滤波器结构之间切换。 因此,编码器不仅可以在插值期间在不同的滤波器结构之间切换,而且提供了一种滤波器结构对,编码器可以利用它来内插宽范围的信号而不增加分接头长度。
