Chronologically Accurate Retrieval for Temporal Grounding of Motion-Language Models

no code implementations22 Jul 2024 Kent Fujiwara, Mikihiro Tanaka, Qing Yu

To achieve better temporal alignment between text and motion, we further propose to use these texts with shuffled sequence of events as negative samples during training to reinforce the motion-language models.

Exploring Vision Transformers for 3D Human Motion-Language Models with Motion Patches

no code implementations CVPR 2024 Qing Yu, Mikihiro Tanaka, Kent Fujiwara

To build a cross-modal latent space between 3D human motion and language, acquiring large-scale and high-quality human motion data is crucial.

Human Interaction Recognition Transfer Learning

Role-Aware Interaction Generation from Textual Description

1 code implementation ICCV 2023 Mikihiro Tanaka, Kent Fujiwara

We claim that certain interactions, which we call asymmetric interactions, involve a relationship between an actor and a receiver, whose motions significantly differ depending on the assigned role.

A Closer Look at Rotation-Invariant Deep Point Cloud Analysis

no code implementations ICCV 2021 Feiran Li, Kent Fujiwara, Fumio Okura, Yasuyuki Matsushita

Recent progress in rotation-invariant point cloud analysis is mainly driven by converting point clouds into their respective canonical poses, and principal component analysis (PCA) is a practical tool to achieve this.

Generalized Shuffled Linear Regression

no code implementations ICCV 2021 Feiran Li, Kent Fujiwara, Fumio Okura, Yasuyuki Matsushita

Therefore, in this work, we generalize the formulation of shuffled linear regression to a broader range of conditions where only part of the data should correspond.

Neural Implicit Embedding for Point Cloud Analysis

no code implementations CVPR 2020 Kent Fujiwara, Taiichi Hashimoto

One neural network is used to embed a portion of the distance field around a point.

Canonical and Compact Point Cloud Representation for Shape Classification

no code implementations13 Sep 2018 Kent Fujiwara, Ikuro Sato, Mitsuru Ambai, Yuichi Yoshida, Yoshiaki Sakakura

We present a novel compact point cloud representation that is inherently invariant to scale, coordinate change and point permutation.
