Inferring Quality in Point Cloud-based 3D Printed Objects using Topological Data Analysis
Paul Rosen, Mustafa Hajij, Junyi Tu +2
Assessing the quality of 3D printed models before they are printed remains a challeng- ing problem, particularly when considering point cloud-based models. This paper introduces an…
Persistent Homology Guided Force-Directed Graph Layouts
Ashley Suh, Mustafa Hajij, Bei Wang +2
Graphs are commonly used to encode relationships among entities, yet their abstractness makes them difficult to analyze. Node-link diagrams are popular for drawing graphs, and forc…
Visual Detection of Structural Changes in Time-Varying Graphs Using Persistent Homology
Mustafa Hajij, Bei Wang, Carlos Scheidegger +1
Topological data analysis is an emerging area in exploratory data analysis and data mining. Its main tool, persistent homology, has become a popular technique to study the structur…
Segmenting a Surface Mesh into Pants Using Morse Theory
Mustafa Hajij, Tamal Dey, Xin Li
A pair of pants is a genus zero orientable surface with three boundary components. A pants decomposition of a surface is a finite collection of unordered pairwise disjoint simple c…
