RiCS: A 2D Self-Occlusion Map for Harmonizing Volumetric Objects

no code implementations14 May 2022 Yunseok Jang, Ruben Villegas, Jimei Yang, Duygu Ceylan, Xin Sun, Honglak Lee

We test the effectiveness of our representation on the human image harmonization task by predicting shading that is coherent with a given background image.

Contact-Aware Retargeting of Skinned Motion

no code implementations ICCV 2021 Ruben Villegas, Duygu Ceylan, Aaron Hertzmann, Jimei Yang, Jun Saito

Self-contacts, such as when hands touch each other or the torso or the head, are important attributes of human body language and dynamics, yet existing methods do not model or preserve these contacts.

Single-image Full-body Human Relighting

no code implementations15 Jul 2021 Manuel Lagunas, Xin Sun, Jimei Yang, Ruben Villegas, Jianming Zhang, Zhixin Shu, Belen Masia, Diego Gutierrez

We present a single-image data-driven method to automatically relight images with full-body humans in them.

Task-Generic Hierarchical Human Motion Prior using VAEs

no code implementations7 Jun 2021 Jiaman Li, Ruben Villegas, Duygu Ceylan, Jimei Yang, Zhengfei Kuang, Hao Li, Yajie Zhao

We demonstrate the effectiveness of our hierarchical motion variational autoencoder in a variety of tasks including video-based human pose estimation, motion completion from partial observations, and motion synthesis from sparse key-frames.

Contact and Human Dynamics from Monocular Video

1 code implementation ECCV 2020 Davis Rempe, Leonidas J. Guibas, Aaron Hertzmann, Bryan Russell, Ruben Villegas, Jimei Yang

Existing deep models predict 2D and 3D kinematic poses from video that are approximately accurate, but contain visible errors that violate physical constraints, such as feet penetrating the ground and bodies leaning at extreme angles.

High Fidelity Video Prediction with Large Stochastic Recurrent Neural Networks

no code implementations NeurIPS 2019 Ruben Villegas, Arkanath Pathak, Harini Kannan, Dumitru Erhan, Quoc V. Le, Honglak Lee

Predicting future video frames is extremely challenging, as there are many factors of variation that make up the dynamics of how frames change through time.

MT-VAE: Learning Motion Transformations to Generate Multimodal Human Dynamics

1 code implementation ECCV 2018 Xinchen Yan, Akash Rastogi, Ruben Villegas, Kalyan Sunkavalli, Eli Shechtman, Sunil Hadap, Ersin Yumer, Honglak Lee

Our model jointly learns a feature embedding for motion modes (that the motion sequence can be reconstructed from) and a feature transformation that represents the transition of one motion mode to the next motion mode.

Hierarchical Long-term Video Prediction without Supervision

no code implementations ICML 2018 Nevan Wichers, Ruben Villegas, Dumitru Erhan, Honglak Lee

Much of recent research has been devoted to video prediction and generation, yet most of the previous works have demonstrated only limited success in generating videos on short-term horizons.

Neural Kinematic Networks for Unsupervised Motion Retargetting

1 code implementation CVPR 2018 Ruben Villegas, Jimei Yang, Duygu Ceylan, Honglak Lee

We propose a recurrent neural network architecture with a Forward Kinematics layer and cycle consistency based adversarial training objective for unsupervised motion retargetting.

Decomposing Motion and Content for Natural Video Sequence Prediction

1 code implementation25 Jun 2017 Ruben Villegas, Jimei Yang, Seunghoon Hong, Xunyu Lin, Honglak Lee

To the best of our knowledge, this is the first end-to-end trainable network architecture with motion and content separation to model the spatiotemporal dynamics for pixel-level future prediction in natural videos.

Learning to Generate Long-term Future via Hierarchical Prediction

2 code implementations ICML 2017 Ruben Villegas, Jimei Yang, Yuliang Zou, Sungryull Sohn, Xunyu Lin, Honglak Lee

To avoid inherent compounding errors in recursive pixel-level prediction, we propose to first estimate high-level structure in the input frames, then predict how that structure evolves in the future, and finally by observing a single frame from the past and the predicted high-level structure, we construct the future frames without having to observe any of the pixel-level predictions.

Improving Object Detection with Deep Convolutional Networks via Bayesian Optimization and Structured Prediction

no code implementations CVPR 2015 Yuting Zhang, Kihyuk Sohn, Ruben Villegas, Gang Pan, Honglak Lee

Object detection systems based on the deep convolutional neural network (CNN) have recently made ground- breaking advances on several object detection benchmarks.
