故本文删去了原算法的裁剪步骤,具体的核心逻辑如下所示: from utils import config_read from heart_seg import affine_registration, bspline_registration train_path_list[id], itk.F)) # 利用B-样条配准对齐患者CT与模板图像 _, transform_parameters = bspline_registration
colour = yarn_company_name), df_base, size = 0.6),sigma = 3) + # 绘制模糊线段 with_blur(geom_bspline0
= bellInterpolation ( -(( (double) n ) - u ) ); } else if(type == BSPLINE
parameters parameters DP were initialized with a value of 0 For all experiments,we used spatial affine and bspline

此外,数据插值的bspline方法用于在[0,72小时]的间隔内插入最多50个时间点的模块表达值。然后,我们在时间t将模块d的表达水平建模为在时间(t-1)处具有其他模块的表达水平的线性回归。
