Through the Perspective of LiDAR: A Feature-Enriched and Uncertainty-Aware Annotation Pipeline for Terrestrial Point Cloud Segmentation
Fei Zhang, Rob Chancia, Josie Clapp +4
Accurate semantic segmentation of terrestrial laser scanning (TLS) point clouds is limited by costly manual annotation. We propose a semi-automated, uncertainty-aware pipeline that…
Uranus' hidden narrow rings
M. M. Hedman, R. O. Chancia
In addition to its suite of narrow dense rings, Uranus is surrounded by an extremely complex system of dusty rings that were most clearly seen by the Voyager spacecraft after it fl…
Photometric analyses of Saturn's small moons: Aegaeon, Methone and Pallene are dark; Helene and Calypso are bright
M. M. Hedman, P. Helfenstein, R. O. Chancia +4
We examine the surface brightnesses of Saturn's smaller satellites using a photometric model that explicitly accounts for their elongated shapes and thus facilitates comparisons am…
Seasonal structures in Saturn's dusty Roche Division correspond to periodicities of the planet's magnetosphere
R. O. Chancia, M. M. Hedman, S. W. H. Cowley +2
We identify multiple periodic dusty structures in Saturn's Roche Division, a faint region spanning the km between the A and F rings. The locations and extent of these fe…
Weighing Uranus' moon Cressida with the ring
Robert O. Chancia, Matthew M. Hedman, Richard G. French
The ring is one of the narrow rings of Uranus, consisting of a dense core that is 1-2 km wide and a diffuse outer sheet spanning about 40 km. Its dense core lies just exterior…
Are there moonlets near the Uranian alpha and beta rings?
R. O. Chancia, M. M. Hedman
The Voyager 2 Radio Science Subsystem occultations of the Uranian alpha and beta rings exhibit quasi-periodic optical depth variations with radial wavelengths that vary with longit…
