我们提出了一种基于模态分析的新的血管轮廓表征和比较技术。每个轮廓都表示为近似其轮廓的节点链，并通过计算其变形谱来表征，即将其转换为参考形状所需的变形量。可以通过计算两个轮廓对应的变形谱向量之间的欧氏距离来比较两个轮廓。我们已经使用专家标记的配置文件数据库完成了监督分类实验。成功率超过 89%，优于其他技术，同时保持较低的计算成本。我们的结果表明，所提出的描述符捕获了给定轮廓的形态特征。
We propose a new vessel profile characterization and comparison technique, based on Modal Analysis. Each profile is represented as a node chain that approximates its contour, and characterized by calculating its deformation spectrum, i.e. the amount of deformation needed to transform it into a reference shape. Two profiles can be compared by computing the Euclidean Distance between their corresponding deformation spectrum vectors. We have done our supervised classification experiments with a profile database labeled by experts. Success rates, which exceed 89 %, are better than the ones obtained by other techniques, while maintaining a low computational cost. Our results suggest that the proposed descriptor captures the morphological features of a given profile.
