Do Egocentric Video-Language Models Capture Both Hand- and Object-Centric Cues?

Masatoshi Tateno, Alexandros Stergiou, Risa Shinoda +2

Hand-object interaction (HOI) recognition requires capturing both hand manipulations and object transformations. However, existing video-language models often fall into shortcuts b…

Zero-shot Hierarchical Plant Segmentation via Foundation Segmentation Models and Text-to-image Attention

Junhao Xing, Ryohei Miyakawa, Yang Yang +5

Foundation segmentation models achieve reasonable leaf instance extraction from top-view crop images without training (i.e., zero-shot). However, segmenting entire plant individual…

GaussianPlant: Structure-aligned Gaussian Splatting for 3D Reconstruction of Plants

Yang Yang, Risa Shinoda, Hiroaki Santo +1

We present a method for jointly recovering the appearance and internal structure of botanical plants from multi-view images based on 3D Gaussian Splatting (3DGS). While 3DGS exhibi…
