A block-based adaptive three stages motion estimation using early termination for anti-shaking
In this paper, a block-based adaptive three stages motion estimation using early termination which is used for anti-shaking is proposed. Low computational complexity and accurate motion estimation are demanded to anti-shaking for mobile phone. Therefore three stages which consist of the predicted motion vector (PMV), the two-bit transform using second derivatives (2BT-SD) and the two steps search (2SS) are performed stage-by-stage. The three stages are early terminated up to result of stage. So the tradeoff between computational complexity and accuracy is mediated by the characteristics of early termination which is determined by characteristics of frames. To evaluate the proposed algorithm, peak signal-to-noise ratio of reconstructed frames and current frames is measured. And the proportions of each stage are used to evaluate computational complexity.
