DiffusionRig: Learning Personalized Priors for Facial Appearance Editing

1 code implementation CVPR 2023 Zheng Ding, Xuaner Zhang, Zhihao Xia, Lars Jebe, Zhuowen Tu, Xiuming Zhang

On a high level, DiffusionRig learns to map simplistic renderings of 3D face models to realistic photos of a given person.

A Loopback Network for Explainable Microvascular Invasion Classification

no code implementations CVPR 2023 Shengxuming Zhang, Tianqi Shi, Yang Jiang, Xiuming Zhang, Jie Lei, Zunlei Feng, Mingli Song

The loopback between two branches enables the category label to supervise the cell locating branch to learn the locating ability for cancerous areas.

Bone marrow sparing for cervical cancer radiotherapy on multimodality medical images

no code implementations20 Apr 2022 Yuening Wang, Ying Sun, Jie Yuan, Kexin Gan, Hanzi Xu, Han Gao, Xiuming Zhang

Experiments on patient dataset reveal that our proposed method can enhance the multimodal image registration accuracy and efficiency for medical practitioners in sparing BM of cervical cancer radiotherapy.

SunStage: Portrait Reconstruction and Relighting using the Sun as a Light Stage

no code implementations CVPR 2023 Yifan Wang, Aleksander Holynski, Xiuming Zhang, Xuaner Zhang

Our method only requires the user to capture a selfie video outdoors, rotating in place, and uses the varying angles between the sun and the face as guidance in joint reconstruction of facial geometry, reflectance, camera pose, and lighting parameters.

Edge-competing Pathological Liver Vessel Segmentation with Limited Labels

1 code implementation1 Aug 2021 Zunlei Feng, Zhonghua Wang, Xinchao Wang, Xiuming Zhang, Lechao Cheng, Jie Lei, Yuexuan Wang, Mingli Song

The diagnosis of MVI needs discovering the vessels that contain hepatocellular carcinoma cells and counting their number in each vessel, which depends heavily on experiences of the doctor, is largely subjective and time-consuming.

Editing Conditional Radiance Fields

1 code implementation ICCV 2021 Steven Liu, Xiuming Zhang, Zhoutong Zhang, Richard Zhang, Jun-Yan Zhu, Bryan Russell

In this paper, we explore enabling user editing of a category-level NeRF - also known as a conditional radiance field - trained on a shape category.

NeRV: Neural Reflectance and Visibility Fields for Relighting and View Synthesis

no code implementations CVPR 2021 Pratul P. Srinivasan, Boyang Deng, Xiuming Zhang, Matthew Tancik, Ben Mildenhall, Jonathan T. Barron

We present a method that takes as input a set of images of a scene illuminated by unconstrained known lighting, and produces as output a 3D representation that can be rendered from novel viewpoints under arbitrary lighting conditions.

Multi-Plane Program Induction with 3D Box Priors

no code implementations NeurIPS 2020 Yikai Li, Jiayuan Mao, Xiuming Zhang, William T. Freeman, Joshua B. Tenenbaum, Noah Snavely, Jiajun Wu

We consider two important aspects in understanding and editing images: modeling regular, program-like texture or patterns in 2D planes, and 3D posing of these planes in the scene.

Neural Light Transport for Relighting and View Synthesis

1 code implementation9 Aug 2020 Xiuming Zhang, Sean Fanello, Yun-Ta Tsai, Tiancheng Sun, Tianfan Xue, Rohit Pandey, Sergio Orts-Escolano, Philip Davidson, Christoph Rhemann, Paul Debevec, Jonathan T. Barron, Ravi Ramamoorthi, William T. Freeman

In particular, we show how to fuse previously seen observations of illuminants and views to synthesize a new image of the same scene under a desired lighting condition from a chosen viewpoint.

Portrait Shadow Manipulation

1 code implementation18 May 2020 Xuaner Cecilia Zhang, Jonathan T. Barron, Yun-Ta Tsai, Rohit Pandey, Xiuming Zhang, Ren Ng, David E. Jacobs

We propose a way to explicitly encode facial symmetry and show that our dataset and training procedure enable the model to generalize to images taken in the wild.

Program-Guided Image Manipulators

no code implementations ICCV 2019 Jiayuan Mao, Xiuming Zhang, Yikai Li, William T. Freeman, Joshua B. Tenenbaum, Jiajun Wu

Humans are capable of building holistic representations for images at various levels, from local objects, to pairwise relations, to global structures.

Image Inpainting

Learning to Reconstruct Shapes from Unseen Classes

no code implementations NeurIPS 2018 Xiuming Zhang, Zhoutong Zhang, Chengkai Zhang, Joshua B. Tenenbaum, William T. Freeman, Jiajun Wu

From a single image, humans are able to perceive the full 3D shape of an object by exploiting learned shape priors from everyday life.

MoSculp: Interactive Visualization of Shape and Time

no code implementations14 Sep 2018 Xiuming Zhang, Tali Dekel, Tianfan Xue, Andrew Owens, Qiurui He, Jiajun Wu, Stefanie Mueller, William T. Freeman

We present a system that allows users to visualize complex human motion via 3D motion sculptures---a representation that conveys the 3D structure swept by a human body as it moves through space.

Learning Shape Priors for Single-View 3D Completion and Reconstruction

no code implementations ECCV 2018 Jiajun Wu, Chengkai Zhang, Xiuming Zhang, Zhoutong Zhang, William T. Freeman, Joshua B. Tenenbaum

The problem of single-view 3D shape completion or reconstruction is challenging, because among the many possible shapes that explain an observation, most are implausible and do not correspond to natural objects.
