| 摘 要： | 周围神经CT图像增强是周围神经三维重建中的基础环节,本文在分析高斯圆模型Hessian矩阵特征值特点的基础上,提出一种基于Hessian矩阵多尺度滤波的周围神经CT图像增强算法.实验证明该方法能够使似圆形周围神经区域得以增强,抑止其他非圆形区域的干扰,得到较好的周围神经增强图像,为后续的分割与三维重建奠定基础.

| Abstract: | Peripheral nerve CT image enhancement is the basis of peripheral nerve 3D reconstruction.This paper puts forward an enhancement algorithm for peripheral nerve image based on multi-scale enhancement filtering of Hessian matrix,by analyzing the characters of eigenvalues of Hessian matrix for Gaussian round model.And the results show that the algorithm enhances areas like circle accurately while suppresses the non-circle disturbance,which will do good to further segmentation and reconstruction. |
