Abstract:
This disclosure provides systems and methods for low complexity quarter pel generation in motion search for video coding. The method can include storing full-pixel position information related to a plurality of rows of video information of a reference frame in a memory. The method can also include applying a vertical interpolation filter to the full-pixel position information for video information related to the reference frame to determine a first sub-pel position information. The method can also include applying a horizontal interpolation filter to the first sub-pel position information to determine a second sub-pel position information for the every other row of video data. The method can also include generating a syntax element indicating pixel motion of a current frame based on the first sub-pel position information. The method can also include encoding a block based on the generated syntax element.
