The traditional block matching method only considers the translation motion. It can not estimate the rational motion correctly.

传统块匹配法只考虑平移运动，对大角度旋转无法进行有效估计。

The experiment shows that the average residual error using the method is smaller than using block matching method for the large scale elastic deformed image.

实验表明，对有较大弹性形变的图像，与块匹配法相比，该算法得到的平均匹配残差明显减小。

As well as, because the shake eliminating method and the optical flow computational method use the same block matching method, the algorithm can save the computing time efficiently.

另外，该方法中抖动消除算法和光流计算方法使用同一块匹配算法，这样能有效地节省了算法的时间。
