TutteNet: Injective 3D Deformations by Composition of 2D Mesh Deformations

no code implementations CVPR 2024 Bo Sun, Thibault Groueix, Chen Song, QiXing Huang, Noam Aigerman

This work proposes a novel representation of injective deformations of 3D space, which overcomes existing limitations of injective methods: inaccuracy, lack of robustness, and incompatibility with general learning and optimization frameworks.

An Optimization Framework to Enforce Multi-View Consistency for Texturing 3D Meshes Using Pre-Trained Text-to-Image Models

no code implementations22 Mar 2024 Zhengyi Zhao, Chen Song, Xiaodong Gu, Yuan Dong, Qi Zuo, Weihao Yuan, Zilong Dong, Liefeng Bo, QiXing Huang

In particular, the third and fourth stages are iterated, with the cuts obtained in the fourth stage encouraging non-rigid alignment in the third stage to focus on regions close to the cuts.

Detecting Any Human-Object Interaction Relationship: Universal HOI Detector with Spatial Prompt Learning on Foundation Models

1 code implementation NeurIPS 2023 Yichao Cao, Qingfei Tang, Xiu Su, Chen Song, Shan You, Xiaobo Lu, Chang Xu

We conduct a deep analysis of the three hierarchical features inherent in visual HOI detectors and propose a method for high-level relation extraction aimed at VL foundation models, which we call HO prompt-based learning.

Multi-View Representation is What You Need for Point-Cloud Pre-Training

no code implementations5 Jun 2023 Siming Yan, Chen Song, Youkang Kong, QiXing Huang

Different from the popular practice of predicting 2D features first and then obtaining 3D features through dimensionality lifting, our approach directly uses a 3D network for feature extraction.

LiDAR-Based 3D Object Detection via Hybrid 2D Semantic Scene Generation

1 code implementation4 Apr 2023 Haitao Yang, Zaiwei Zhang, Xiangru Huang, Min Bai, Chen Song, Bo Sun, Li Erran Li, QiXing Huang

Bird's-Eye View (BEV) features are popular intermediate scene representations shared by the 3D backbone and the detector head in LiDAR-based object detectors.

DeblurSR: Event-Based Motion Deblurring Under the Spiking Representation

1 code implementation15 Mar 2023 Chen Song, Chandrajit Bajaj, QiXing Huang

We additionally show that our approach easily extends to video super-resolution when combined with recent advances in implicit neural representation.

Comparison and Analysis of Cognitive Load under 2D/3D Visual Stimuli

no code implementations25 Feb 2023 Yu Liu, Chen Song, Yunpeng Yin, Herui Shi, Jinglin Sun, Han Wang, Peiguang Jing

According to our experiments and analysis, videos that involve simple observational tasks (P <0. 05) consistently induced a higher cognitive load in subjects when they were viewing 3D videos.

HybridPose: 6D Object Pose Estimation under Hybrid Representations

3 code implementations CVPR 2020 Chen Song, Jiaru Song, Qi-Xing Huang

Compared to a unitary representation, our hybrid representation allows pose regression to exploit more and diverse features when one type of predicted representation is inaccurate (e. g., because of occlusion).

Image Dataset for Visual Objects Classification in 3D Printing

no code implementations15 Feb 2018 Hongjia Li, Xiaolong Ma, Aditya Singh Rathore, Zhe Li, Qiyuan An, Chen Song, Wenyao Xu, Yanzhi Wang

The rapid development in additive manufacturing (AM), also known as 3D printing, has brought about potential risk and security issues along with significant benefits.
