Parameter-Efficient Orthogonal Finetuning via Butterfly Factorization

1 code implementation10 Nov 2023 Weiyang Liu, Zeju Qiu, Yao Feng, Yuliang Xiu, Yuxuan Xue, Longhui Yu, Haiwen Feng, Zhen Liu, Juyeon Heo, Songyou Peng, Yandong Wen, Michael J. Black, Adrian Weller, Bernhard Schölkopf

We apply this parameterization to OFT, creating a novel parameter-efficient finetuning method, called Orthogonal Butterfly (BOFT).

Ghost on the Shell: An Expressive Representation of General 3D Shapes

no code implementations23 Oct 2023 Zhen Liu, Yao Feng, Yuliang Xiu, Weiyang Liu, Liam Paull, Michael J. Black, Bernhard Schölkopf

Recent work has focused on the former, and methods for reconstructing open surfaces do not support fast reconstruction with material and lighting or unconditional generative modelling.

TADA! Text to Animatable Digital Avatars

no code implementations21 Aug 2023 Tingting Liao, Hongwei Yi, Yuliang Xiu, Jiaxaing Tang, Yangyi Huang, Justus Thies, Michael J. Black

We introduce TADA, a simple-yet-effective approach that takes textual descriptions and produces expressive 3D avatars with high-quality geometry and lifelike textures, that can be animated and rendered with traditional graphics pipelines.

D-IF: Uncertainty-aware Human Digitization via Implicit Distribution Field

1 code implementation ICCV 2023 Xueting Yang, Yihao Luo, Yuliang Xiu, Wei Wang, Hao Xu, Zhaoxin Fan

In this paper, we propose replacing the implicit value with an adaptive uncertainty distribution, to differentiate between points based on their distance to the surface.

TeCH: Text-guided Reconstruction of Lifelike Clothed Humans

1 code implementation16 Aug 2023 Yangyi Huang, Hongwei Yi, Yuliang Xiu, Tingting Liao, Jiaxiang Tang, Deng Cai, Justus Thies

But how to effectively capture all visual attributes of an individual from a single image, which are sufficient to reconstruct unseen areas (e. g., the back view)?

Descriptive Question Answering +1

ECON: Explicit Clothed humans Optimized via Normal integration

1 code implementation CVPR 2023 Yuliang Xiu, Jinlong Yang, Xu Cao, Dimitrios Tzionas, Michael J. Black

To increase robustness for these cases, existing work uses an explicit parametric body model to constrain surface reconstruction, but this limits the recovery of free-form surfaces such as loose clothing that deviates from the body.

DART: Articulated Hand Model with Diverse Accessories and Rich Textures

1 code implementation14 Oct 2022 Daiheng Gao, Yuliang Xiu, Kailin Li, Lixin Yang, Feng Wang, Peng Zhang, Bang Zhang, Cewu Lu, Ping Tan

Unity GUI is also provided to generate synthetic hand data with user-defined settings, e. g., pose, camera, background, lighting, textures, and accessories.

Monocular Real-Time Volumetric Performance Capture

1 code implementation ECCV 2020 Ruilong Li, Yuliang Xiu, Shunsuke Saito, Zeng Huang, Kyle Olszewski, Hao Li

We present the first approach to volumetric performance capture and novel-view rendering at real-time speed from monocular video, eliminating the need for expensive multi-view systems or cumbersome pre-acquisition of a personalized template model.

Pose Flow: Efficient Online Pose Tracking

1 code implementation3 Feb 2018 Yuliang Xiu, Jiefeng Li, Haoyu Wang, Yinghong Fang, Cewu Lu

Multi-person articulated pose tracking in unconstrained videos is an important while challenging problem.
