| 摘 要： | 该文将脉冲耦合神经网络模型从二维平面扩展到三维空间，同时提出一种新的乘积型互信息算法，将其作为脉冲耦合神经网络分割算法的最优分割准则，并将两者结合实现三维医学图像的整体自动分割. 利用该文提出的算法对三维CT肺部图像进行分割实验，结果表明，该算法在保证分割精度的基础上显著地减少了分割运行时间，提高了分割效率，具有应用于医学图像分割的潜在价值.

| Abstract: | In this study, the 2D pulse coupled neural network (PCNN) model is extended to the 3D space, and a new rule for optimal image segmentation, named product mutual information (PMI), is proposed. Based on the 3D PCNN and PMI, an automatic segmentation algorithm is developed for 3D medical image segmentation. Three-dimensional CT lung images are segmented with the proposed method, showing reduced execution time and improved computation efficiency with high segmentation accuracy. The method is potentially useful formedical image segmentation. |
