本文提出了一种计算三维欧氏空间中生物器官平均图像的变分方法。三维生物器官的平均值是区分异常器官和正常器官的基本特征。我们结合联合收割机的扩散配准技术和光流计算的平均值和每个输入器官之间的空间变形场的计算。我们将平均值定义为使总变形最小的形状。
In this paper, we develop a variational method for the computation of average images of biological organs in three-dimensional Euclidean space. The average of three-dimensional biological organs is an essential feature to discriminate abnormal organs from normal organs. We combine the diffusion registration technique and optical flow computation for the computation of spatial deformation field between the averages and each input organ. We define the average as the shape which minimises the total deformation.
