追踪图像数据中拓扑特征的时间演化

研究问题
如何在图像序列中同时判断拓扑特征的空间与时间显著性,并描述连通分量、环等特征的出现、持续和变化?
方法与思路
作者提出时空联合的拓扑假设检验框架,利用加入时间后产生的高维拓扑连接,并以 zigzag 持续图概括低维特征的演化。
材料陈述的贡献
摘要称方法能捕捉受损细胞修复中的拓扑特征演进,并在包含伤口愈合特征的模拟中优于一个现有方法。
阅读关注点
应核对显著拓扑特征的零假设、时空依赖和多重比较处理,以及持续图构造与模拟比较是否对应真实修复过程。
阅读边界
这是 arXiv 预印本,同行评审与期刊接收未核实;摘要未说明检验校准、误差控制及比较数值,不能将模拟优势推广到其他图像任务。

原文摘要

Topological Data Analysis (TDA) can be used to detect and characterize holes in an image, such as zero-dimensional holes (connected components) or one-dimensional holes (loops). However, there is currently no widely accepted statistical framework for modeling spatiotemporal dependence in the evolution of topological features, such as holes, within a time series of images. We propose a hypothesis testing framework to identify statistically significant topological features of images in space and time, simultaneously. This addition of time may induce higher-dimensional topological features which can be used to establish temporal connections between the lower-dimensional features at each point in time. The temporal evolution of these lower-dimensional features is then represented on a zigzag persistence diagram, as a topological summary statistic focused on time dynamics. We demonstrate that the method effectively captures the emergence and progression of topological features in a study of a series of images of a wounded cell as it repairs. The proposed method outperforms a current approach in a simulation study that includes features of the wound healing process. Since, the wounded cell images exhibit nonlinear, dynamic, spatial, and temporal structures during single-cell repair, they provide a good application for this method.
