Motion estimation based on pre-filter iterative gradient method

提出一种对小平移和大平移图像序列进行运动估计的新算法 预滤波迭代梯度法,预滤波迭代梯度法就是先对图像进行低通滤波,然后用迭代梯度法进行运动估计。结果表明,该方法比梯度法、预滤波梯度法和迭代梯度法具有更高的估计精度,而且可以很好地抑制噪声的影响。

The pre-filter iterative gradient method for estimating motion in image sequences with small and large displacements is presented, which pre-filter the images with a low pass filter and motion estimation is performed using the iterative gradient method. The experimental results show that the new algorithm is more accurate than gradient method, pre-filter gradient method and iterative gradient method and can greatly retrain the effect of noise.
