| 摘 要： | 文章在图割理论的基础上,引入了一种新的方法将图割理论和改进的变分水平集模型结合起来,先利用图割理论对目标形成一个初始轮廓,并在得到的轮廓线上定义能量函数,通过能量函数的最小化,从而使得到的轮廓线最终收敛到目标边界,这样在保证分割精度的同时大大简化了计算量. |

| Abstract: | On the basis of the theory of graph cuts,the introduction of a new approach to graph cuts theory and improved variational level set models combine first use of the theory of graph cut to form an initial outline of the target,and in the contourdefine the energy function,the minimization of the energy function,so that the contour lines eventually converge to the target boundary,so to ensure the accuracy of segmentation at the same time greatly simplify the calculation. |
