PanoImager: Geometry-Guided Novel View Synthesis and Reconstruction from Sparse Panoramic Views
Zhisong Xu, Takeshi Oishi
Panoramic sensing offers wide field-of-view coverage, yet 3D reconstruction from sparse panoramas remains challenging under rotation-dominant, weak-parallax motion. In such regimes…
ScanDP: Generalizable 3D Scanning with Diffusion Policy
Itsuki Hirako, Ryo Hakoda, Yubin Liu +3
Learning-based 3D Scanning plays a crucial role in enabling efficient and accurate scanning of target objects. However, recent reinforcement learning-based methods often require la…
FrameVGGT: Coherence-Preserving Memory for Bounded Streaming Geometry
Zhisong Xu, Takeshi Oishi
Streaming Visual Geometry Transformers such as StreamVGGT enable strong online 3D perception, but their KV-cache grows unbounded over long streams, limiting practical deployment. W…
REF-NeRF: Reflection and Refraction aware Neural Radiance Field
Wooseok Kim, Taiki Fukiage, Takeshi Oishi
Recently, significant progress has been made in the study of methods for 3D reconstruction from multiple images using implicit neural representations, exemplified by the neural rad…
