重建之前 meaning in Chinese

beofre the restoration

Secondly , we study the preprocessing part of system , a method of bidirectional multi - resolution motion estimation via radon transform is proposed , which can be used to estimate both pixel and subpixel motion vectors with robustly accurately and efficiently . bad frames elimination via the variances of lr frames in the sequence is preformed before the implementation of the super - resolution algorithm
其次讨论了超分辨预处理过程,提出了基于radon变换的双方向多分辨率运动估计方法,算法可以稳健、精确的在较大范围内实现亚象素运动估计;以图像方差为标准,判断序列图像中个别帧损坏严重为“坏帧” ,在超分辨重建之前预先去除。
