Abstract

We introduce a narrow band region approach for explicit deformable models in the perspective of 2D and 3D image segmentation. Embedding a region term into the evolution process, we derive a general framework which is applied both on a 2D parametric contour and a 3D triangular mesh. Evolution of deformable models is performed by means of energy minimization using the computationally efficient greedy algorithm. The use of a region energy related to the vicinity of the evolving surface overcomes limitations of edge-based active models while remaining time effective. Experiments with segmentation quality assessment are carried out on medical data sets.
活动轮廓和曲面的窄带区域方法
从二维和三维图像分割的角度介绍了一种用于显式可变形模型的窄带区域方法。在演化过程中嵌入一个区域项,推导出一个适用于二维参数化轮廓和三维三角网格的通用框架。可变形模型的演化采用计算效率高的贪心算法进行能量最小化。利用与演化曲面附近相关的区域能量克服了基于边缘的活动模型的局限性,同时保持了时间有效性。在医学数据集上进行了分割质量评价实验。
