Gaussian Shadow Casting for Neural Characters

no code implementations11 Jan 2024 Luis Bolanos, Shih-Yang Su, Helge Rhodin

Combined with a deferred neural rendering model, our Gaussian shadows enable Lambertian shading and shadow casting with minimal overhead.

Mirror-Aware Neural Humans

no code implementations9 Sep 2023 Daniel Ajisafe, James Tang, Shih-Yang Su, Bastian Wandt, Helge Rhodin

Human motion capture either requires multi-camera systems or is unreliable using single-view input due to depth ambiguities.

NPC: Neural Point Characters from Video

no code implementations ICCV 2023 Shih-Yang Su, Timur Bagautdinov, Helge Rhodin

Previous methods avoid using a template but rely on a costly or ill-posed mapping from observation to canonical space.

UNeRF: Time and Memory Conscious U-Shaped Network for Training Neural Radiance Fields

no code implementations23 Jun 2022 Abiramy Kuganesan, Shih-Yang Su, James J. Little, Helge Rhodin

Neural Radiance Fields (NeRFs) increase reconstruction detail for novel view synthesis and scene reconstruction, with applications ranging from large static scenes to dynamic human motion.

DANBO: Disentangled Articulated Neural Body Representations via Graph Neural Networks

no code implementations3 May 2022 Shih-Yang Su, Timur Bagautdinov, Helge Rhodin

While a few such approaches exist, those have limited generalization capabilities and are prone to learning spurious (chance) correlations between irrelevant body parts, resulting in implausible deformations and missing body parts on unseen poses.

Image Generation

3D Photography using Context-aware Layered Depth Inpainting

1 code implementation CVPR 2020 Meng-Li Shih, Shih-Yang Su, Johannes Kopf, Jia-Bin Huang

We propose a method for converting a single RGB-D input image into a 3D photo - a multi-layer representation for novel view synthesis that contains hallucinated color and depth structures in regions occluded in the original view.

Graph Generation with Variational Recurrent Neural Network

no code implementations2 Oct 2019 Shih-Yang Su, Hossein Hajimirsadeghi, Greg Mori

Generating graph structures is a challenging problem due to the diverse representations and complex dependencies among nodes.

Diversity-Driven Exploration Strategy for Deep Reinforcement Learning

no code implementations NeurIPS 2018 Zhang-Wei Hong, Tzu-Yun Shann, Shih-Yang Su, Yi-Hsiang Chang, Chun-Yi Lee

Efficient exploration remains a challenging research problem in reinforcement learning, especially when an environment contains large state spaces, deceptive local optima, or sparse rewards.

Virtual-to-Real: Learning to Control in Visual Semantic Segmentation

no code implementations1 Feb 2018 Zhang-Wei Hong, Chen Yu-Ming, Shih-Yang Su, Tzu-Yun Shann, Yi-Hsiang Chang, Hsuan-Kung Yang, Brian Hsi-Lin Ho, Chih-Chieh Tu, Yueh-Chuan Chang, Tsu-Ching Hsiao, Hsin-Wei Hsiao, Sih-Pin Lai, Chun-Yi Lee

Collecting training data from the physical world is usually time-consuming and even dangerous for fragile robots, and thus, recent advances in robot learning advocate the use of simulators as the training platform.

A Deep Policy Inference Q-Network for Multi-Agent Systems

no code implementations21 Dec 2017 Zhang-Wei Hong, Shih-Yang Su, Tzu-Yun Shann, Yi-Hsiang Chang, Chun-Yi Lee

DPIQN incorporates the learned policy features as a hidden vector into its own deep Q-network (DQN), such that it is able to predict better Q values for the controllable agents than the state-of-the-art deep reinforcement learning models.
