早期的实验都是在低分辨率的条件下进行的。

The early experiments were done with low resolution.

本文中首次尝试了在频率域算法中加入金字塔模型，对原本低分辨率图像进行若干次下采样后层层配准提高精度。

In this paper, it is the first time for us to add the pyramid model to the algorithm by Vandewalle et al. to increase the accuracy by coarse-to-fine registering layered down-sampled images.
