Abstract:
A sub-pixel interpolation technique is provided for motion vector estimation during video coding. In one embodiment, this is accomplished by interpolating adjacent pixels at fractional horizontal, vertical, and diagonal locations in a macroblock of (M×N) pixels, such that there are no overlapping interpolations, to generate values for sub-pixels associated with the macroblock of (M×N) pixels.
