BID: Boundary-Interior Decoding for Unsupervised Temporal Action Localization Pre-Trainin

no code implementations12 Mar 2024 Qihang Fang, Chengcheng Tang, Shugao Ma, Yanchao Yang

Skeleton-based motion representations are robust for action localization and understanding for their invariance to perspective, lighting, and occlusion, compared with images.

Temporal Action Localization Unsupervised Pre-training

EMDB: The Electromagnetic Database of Global 3D Human Pose and Shape in the Wild

1 code implementation ICCV 2023 Manuel Kaufmann, Jie Song, Chen Guo, Kaiyue Shen, Tianjian Jiang, Chengcheng Tang, Juan Zarate, Otmar Hilliges

EMDB is a novel dataset that contains high-quality 3D SMPL pose and shape parameters with global body and camera trajectories for in-the-wild videos.

Pose Estimation

PressureVision++: Estimating Fingertip Pressure from Diverse RGB Images

no code implementations5 Jan 2023 Patrick Grady, Jeremy A. Collins, Chengcheng Tang, Christopher D. Twigg, Kunal Aneja, James Hays, Charles C. Kemp

We present a novel approach that enables diverse data to be captured with only an RGB camera and a cooperative participant.

MotionDeltaCNN: Sparse CNN Inference of Frame Differences in Moving Camera Videos with Spherical Buffers and Padded Convolutions

no code implementations ICCV 2023 Mathias Parger, Chengcheng Tang, Thomas Neff, Christopher D. Twigg, Cem Keskin, Robert Wang, Markus Steinberger

Moving cameras add new challenges in how to fuse newly unveiled image regions with already processed regions efficiently to minimize the update rate - without increasing memory overhead and without knowing the camera extrinsics of future frames.

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.

MotionDeltaCNN: Sparse CNN Inference of Frame Differences in Moving Camera Videos

no code implementations18 Oct 2022 Mathias Parger, Chengcheng Tang, Thomas Neff, Christopher D. Twigg, Cem Keskin, Robert Wang, Markus Steinberger

Moving cameras add new challenges in how to fuse newly unveiled image regions with already processed regions efficiently to minimize the update rate - without increasing memory overhead and without knowing the camera extrinsics of future frames.

PressureVision: Estimating Hand Pressure from a Single RGB Image

1 code implementation19 Mar 2022 Patrick Grady, Chengcheng Tang, Samarth Brahmbhatt, Christopher D. Twigg, Chengde Wan, James Hays, Charles C. Kemp

We also show that the output of our model depends on the appearance of the hand and cast shadows near contact regions.

DeltaCNN: End-to-End CNN Inference of Sparse Frame Differences in Videos

no code implementations CVPR 2022 Mathias Parger, Chengcheng Tang, Christopher D. Twigg, Cem Keskin, Robert Wang, Markus Steinberger

With DeltaCNN, we present a sparse convolutional neural network framework that enables sparse frame-by-frame updates to accelerate video inference in practice.

ContactOpt: Optimizing Contact to Improve Grasps

1 code implementation CVPR 2021 Patrick Grady, Chengcheng Tang, Christopher D. Twigg, Minh Vo, Samarth Brahmbhatt, Charles C. Kemp

Given a hand mesh and an object mesh, a deep model trained on ground truth contact data infers desirable contact across the surfaces of the meshes.

DeepSpline: Data-Driven Reconstruction of Parametric Curves and Surfaces

2 code implementations12 Jan 2019 Jun Gao, Chengcheng Tang, Vignesh Ganapathi-Subramanian, Jiahui Huang, Hao Su, Leonidas J. Guibas

Reconstruction of geometry based on different input modes, such as images or point clouds, has been instrumental in the development of computer aided design and computer graphics.

Parsing Geometry Using Structure-Aware Shape Templates

1 code implementation 3D Vision 2018 2018 Vignesh Ganapathi-Subramanian, Olga Diamanti, Soeren Pirk, Chengcheng Tang, Matthias Niessner, Leonidas J. Guibas

Real-life man-made objects often exhibit strong and easily-identifiable structure, as a direct result of their design or their intended functionality.
