Topo-GS: Continuous Volumetric Embedding of High-Dimensional Data via Topological Gaussian Splatting
João Paulo Gois, Luis Gustavo Nonato
Dimensionality reduction algorithms map high-dimensional data into visualizable 2D or 3D spaces, but traditionally rely on a discrete point-cloud paradigm. This discrete abstractio…
TiVy: Time Series Visual Summary for Scalable Visualization
Gromit Yeuk-Yin Chan, Luis Gustavo Nonato, Themis Palpanas +2
Visualizing multiple time series presents fundamental tradeoffs between scalability and visual clarity. Time series capture the behavior of many large-scale real-world processes, f…
Time Series Information Visualization -- A Review of Approaches and Tools
Evandro S. Ortigossa, Fábio F. Dias, Diego C. Nascimento +1
Time series data are prevalent across various domains and often encompass large datasets containing multiple time-dependent features in each sample. Exploring time-varying data is…
TopoMap++: A faster and more space efficient technique to compute projections with topological guarantees
Vitoria Guardieiro, Felipe Inagaki de Oliveira, Harish Doraiswamy +2
High-dimensional data, characterized by many features, can be difficult to visualize effectively. Dimensionality reduction techniques, such as PCA, UMAP, and t-SNE, address this ch…
TopoMap: A 0-dimensional Homology Preserving Projection of High-Dimensional Data
Harish Doraiswamy, Julien Tierny, Paulo J. S. Silva +2
Multidimensional Projection is a fundamental tool for high-dimensional data analytics and visualization. With very few exceptions, projection techniques are designed to map data fr…
GLoG: Laplacian of Gaussian for Spatial Pattern Detection in Spatio-Temporal Data
Luis Gustavo Nonato, Fabiano Petronetto e Claudio Silva
Boundary detection has long been a fundamental tool for image processing and computer vision, supporting the analysis of static and time-varying data. In this work, we built upon t…
Motion Browser: Visualizing and Understanding Complex Upper Limb Movement Under Obstetrical Brachial Plexus Injuries
Gromit Yeuk-Yin Chan, Luis Gustavo Nonato, Alice Chu +3
The brachial plexus is a complex network of peripheral nerves that enables sensing from and control of the movements of the arms and hand. Nowadays, the coordination between the mu…
