图1 (a)成对配准（PW）和(b)群组配准（GW）图像配准示意图．(a)中M代表浮动图像，F为一组图像中任意一幅图像作为模板，φ为变形场，(b)中模板由数据集中N幅图像信息联合构建

Fig.1 Schematic diagrams of image registration for (a) PW and (b) GW. In Fig. (a), M represents a moving image, F represents any image in the group image as a template, and φ is the deformation field. In Fig. (b), the template is jointly constructed by N images in the data set
