A novel all binary motion estimation (ABME)

We present a fast motion estimation algorithm using only binary representation, which is desirable for both embedded system software optimization and hardware implementation with parallel architectures. Our experimental results have showed that it provides excellent performance at both low and high bitrates. Because of its binary only representation, the proposed algorithm offers low computational complexity and low memory bandwidth consumption. For multimedia embedded system design, we further investigated a specific implementation technique with an example of Intel x86 processors. Finally we show that binarization methods are closely coupled to the accuracy of binary motion estimation algorithms. The binarization and coding efficiencies can be improved using various filters and binarization methods
