| 图3 概率生成模型图解．白圈表示隐含变量，灰圈表示观测值（输入图像），方块表示参数．虚线矩形框表示里面的变量x、y、z独立重复N次．配准先验由高斯参数的均值μz和协方差Σz定义 |
| Fig.3 Probability generation model. White circle represents hidden variable, gray circle represents observed value (input image), and squares represent parameters. Dashed rectangle indicates the number of independent repeats N of the x, y, z variables inside. Registration prior is defined by the mean value μz and covariance Σz of Gaussian parameters |
