在心脏图像分析中，重建骨小梁（即末端附着于心室壁的细肌柱）是重要但具有挑战性的。为了提取这些精细结构，传统的图像分割方法是不够的。在本文中，我们提出了一种新的方法来联合检测显着的拓扑手柄，并计算它们的最佳表示。检测到的手柄被认为是假设的小梁结构。它们使用分类器进一步筛选，然后包含在最终分割中。我们在实验中显示，我们的贡献与以前的标准分割方法相比，没有拓扑先验的意义，以及与以前的拓扑方法，其中使用非最佳表示的拓扑手柄。
In cardiac image analysis, it is important yet challenging to reconstruct the trabeculae, namely, fine muscle columns whose ends are attached to the ventricular walls. To extract these fine structures, traditional image segmentation methods are insufficient. In this paper, we propose a novel method to jointly detect salient topological handles and compute the optimal representations of them. The detected handles are considered hypothetical trabeculae structures. They are further screened using a classifier and are then included in the final segmentation. We show in experiments the significance of our contribution compared with previous standard segmentation methods without topological priors, as well as with previous topological method in which non-optimal representations of topological handles are used.
