Structure-aware Riemannian Growth Fields for 4D Plant Modeling
Meng-Yu Jennifer Kuo, Ryo Kawahara
In this paper, we introduce a novel framework for 4D plant growth modeling that reconstructs the continuous geometric and topological evolution of plants from sparse temporal obser…
Action Motifs: Self-Supervised Hierarchical Representation of Human Body Movements
Genki Kinoshita, Shu Nakamura, Ryo Kawahara +3
Effective human behavior modeling requires a representation of the human body movement that capitalizes on its compositionality. We propose a hierarchical representation consisting…
REACH: Hand Pose Estimation from Room Corners
Shu Nakamura, Ryo Kawahara, Genki Kinoshita +4
We introduce a novel 3D hand pose estimator that can accurately recover the shape and pose of people's hands in a room from afar, typically from fixed cameras at room corners, in e…
Appearance and Shape from Water Reflection
Ryo Kawahara, Meng-Yu Jennifer Kuo, Shohei Nobuhara +1
This paper introduces single-image geometric and appearance reconstruction from water reflection photography, i.e., images capturing direct and water-reflected real-world scenes. W…
