Evidence for Suppressed Non-thermal Broadening in a Flare Ribbon from Stereoscopic Observations
Ziwen Huang, L. P. Chitta, L. Teriaca
Flare ribbons mark the footpoints of newly reconnected magnetic loops and are commonly associated with strong plasma flows and enhanced non-thermal broadening of transition-region…
FunArt: Decoding Functional Structure and Articulation from Generative 3D Latents
Dennis Rotondi, Abdelrhman Werby, Kai O. Arras
To operate effectively in human environments, robots must identify articulated objects, segment their movable and interactive parts, and estimate their kinematic models. Existing a…
GESTO: Human-Centric Spatio-Temporal Memory for Reasoning in Dynamic Scenes
Ermanno Bartoli, Buwei He, Dennis Rotondi +6
Robots operating in human environments need memories that capture not only what objects exist and where, but also how people use them over time and how individual interactions comp…
3D Scene Graphs: Open Challenges and Future Directions
Dennis Rotondi, Francesco Argenziano, Sebastian Koch +10
3D Scene Graphs (3DSGs) have emerged as a powerful representation for spatial AI by combining geometric grounding with semantic and relational abstractions of the environment. Thei…
KeySG: Hierarchical Keyframe-Based 3D Scene Graphs
Abdelrhman Werby, Dennis Rotondi, Fabio Scaparro +1
In recent years, 3D scene graphs have emerged as a powerful world representation, offering both geometric accuracy and semantic richness. Combining 3D scene graphs with large langu…
Social 3D Scene Graphs: Modeling Human Actions and Relations for Interactive Service Robots
Ermanno Bartoli, Dennis Rotondi, Buwei He +3
Understanding how people interact with their surroundings and each other is essential for enabling robots to act in socially compliant and context-aware ways. While 3D Scene Graphs…
Long-Term Planning Around Humans in Domestic Environments with 3D Scene Graphs
Ermanno Bartoli, Dennis Rotondi, Kai O. Arras +1
Long-term planning for robots operating in domestic environments poses unique challenges due to the interactions between humans, objects, and spaces. Recent advancements in traject…
FunGraph: Functionality Aware 3D Scene Graphs for Language-Prompted Scene Interaction
Dennis Rotondi, Fabio Scaparro, Hermann Blum +1
The concept of 3D scene graphs is increasingly recognized as a powerful semantic and hierarchical representation of the environment. Current approaches often address this at a coar…
