Abstract:
Methods and systems for video image coding are provided. Sets of filters may be selected and applied to video information at least partially based on phase displacement information between a first and second layer of video information. For example, the phase displacement information may correspond to a difference between a position of a pixel in the first layer and a corresponding position of the pixel in the second layer. The selected filter set can be an up-sampling filter or a down-sampling filter. The phase displacement information may be encoded as a syntax element embedded in the video bit stream.
