Abstract:
Abstract: For solving the problem of traditional back-propagation (BP) neural network for blood vessel segmentation, such as time consuming and low recognition rate, a BP neural network based on Stein-Weiss analytic function is proposed for blood vessel segmentation. After Stein-Weiss function is constructed for each voxel, 16 eigenvalues of the corresponding voxel are calculated according to the analytic properties of Stein-Weiss analytic function. The calculated eigenvalues are taken as the input data of BP neural network, and then the data are classified and learned through the self-learning ability of BP neural network. Finally, the edge of blood vessel is obtained by the generalization ability of BP neural network. The experimental results of hepatic vessel segmentation show that compared with traditional BP neural network algorithms, the proposed algorithm can be used to not only obtain the edge of blood vessel with high recognition rate and rich details, but also improve the efficiency of segmentation.
