EgoPoseFormer: A Simple Baseline for Egocentric 3D Human Pose Estimation

no code implementations26 Mar 2024 Chenhongyi Yang, Anastasia Tkach, Shreyas Hampali, Linguang Zhang, Elliot J. Crowley, Cem Keskin

We also show that our method can be seamlessly extended to monocular settings, which achieves state-of-the-art performance on the SceneEgo dataset, improving MPJPE by 25. 5mm (21% improvement) compared to the best existing method with only 60. 7% model parameters and 36. 4% FLOPs.

Social Diffusion: Long-term Multiple Human Motion Anticipation

1 code implementation ICCV 2023 Julian Tanke, Linguang Zhang, Amy Zhao, Chengcheng Tang, Yujun Cai, Lezi Wang, Po-Chen Wu, Juergen Gall, Cem Keskin

We propose Social Diffusion, a novel method for short-term and long-term forecasting of the motion of multiple persons as well as their social interactions.

UmeTrack: Unified multi-view end-to-end hand tracking for VR

no code implementations31 Oct 2022 Shangchen Han, Po-Chen Wu, Yubo Zhang, Beibei Liu, Linguang Zhang, Zheng Wang, Weiguang Si, Peizhao Zhang, Yujun Cai, Tomas Hodan, Randi Cabezas, Luan Tran, Muzaffer Akbay, Tsz-Ho Yu, Cem Keskin, Robert Wang

In this paper, we present a unified end-to-end differentiable framework for multi-view, multi-frame hand tracking that directly predicts 3D hand pose in world space.

Identity-Aware Hand Mesh Estimation and Personalization from RGB Images

1 code implementation22 Sep 2022 Deying Kong, Linguang Zhang, Liangjian Chen, Haoyu Ma, Xiangyi Yan, Shanlin Sun, Xingwei Liu, Kun Han, Xiaohui Xie

In this paper, we propose an identity-aware hand mesh estimation model, which can incorporate the identity information represented by the intrinsic shape parameters of the subject.

Neural Correspondence Field for Object Pose Estimation

no code implementations30 Jul 2022 Lin Huang, Tomas Hodan, Lingni Ma, Linguang Zhang, Luan Tran, Christopher Twigg, Po-Chen Wu, Junsong Yuan, Cem Keskin, Robert Wang

Unlike classical correspondence-based methods which predict 3D object coordinates at pixels of the input image, the proposed method predicts 3D object coordinates at 3D query points sampled in the camera frustum.

Learning Local Descriptors With a CDF-Based Dynamic Soft Margin

no code implementations ICCV 2019 Linguang Zhang, Szymon Rusinkiewicz

The triplet loss is adopted by a variety of learning tasks, such as local feature descriptor learning.

Accelerating Large-Kernel Convolution Using Summed-Area Tables

no code implementations26 Jun 2019 Linguang Zhang, Maciej Halber, Szymon Rusinkiewicz

In this work, we explore using learnable box filters to allow for convolution with arbitrarily large kernel size, while keeping the number of parameters per filter constant.

Learning to Detect Features in Texture Images

no code implementations CVPR 2018 Linguang Zhang, Szymon Rusinkiewicz

Local feature detection is a fundamental task in computer vision, and hand-crafted feature detectors such as SIFT have shown success in applications including image-based localization and registration.

Image-Based Localization

High-Precision Localization Using Ground Texture

no code implementations29 Oct 2017 Linguang Zhang, Adam Finkelstein, Szymon Rusinkiewicz

We introduce an image-based global localization system that is accurate to a few millimeters and performs reliable localization both indoors and outside.

Robot In a Room: Toward Perfect Object Recognition in Closed Environments

no code implementations9 Jul 2015 Shuran Song, Linguang Zhang, Jianxiong Xiao

By constraining a robot to stay in a limited territory, we can ensure that the robot has seen most objects before and the speed of introducing a new object is slow.

3D ShapeNets: A Deep Representation for Volumetric Shapes

no code implementations CVPR 2015 Zhirong Wu, Shuran Song, Aditya Khosla, Fisher Yu, Linguang Zhang, Xiaoou Tang, Jianxiong Xiao

Our model, 3D ShapeNets, learns the distribution of complex 3D shapes across different object categories and arbitrary poses from raw CAD data, and discovers hierarchical compositional part representations automatically.
