Fast Sub-Pixel Motion Estimation Via One-Bit Transform

In this study sub-pixel motion estimation via one-bit transform is proposed. Low-bit resolution representations exist in literature for motion estimation. However sub-pixel motion estimation employing these kinds of transforms has not tried until now. One-bit (1BT) transform based motion estimation can give inaccurate result for block size of 8times8. Half and quarter pixel motion vectors can be calculated using one-bit transform. In this work higher performance is achieved computing half and quarter pixel motion vectors utilizing one-bit transform than pure one-bit motion estimation
