One-Bit Transform (1BT) and Two-Bit Transform (2BT) based block motion estimation (ME) schemes have been presented in the literature to reduce the computational complexity of motion estimation by making use of low bit-depth representations of video frames and hardware suitable matching. This paper demonstrates that the full potential of 2BT based motion estimation has not been exploited so far and...
Binary motion estimation algorithms reduce the computational complexity of motion estimation, but, sometimes generate an inaccurate motion vector. This paper proposes a novel two-bit representation, called twobit transform-second derivatives (2BT-SD) which improves the efficiency of image binarization and the accuracy of motion estimation by making use of the positive and negative second derivatives...
