Multiresolution Deep Implicit Functions for 3D Shape Representation

no code implementations12 Sep 2021 Zhang Chen, yinda zhang, Kyle Genova, Sean Fanello, Sofien Bouaziz, Christian Haene, Ruofei Du, Cem Keskin, Thomas Funkhouser, Danhang Tang

To the best of our knowledge, MDIF is the first deep implicit function model that can at the same time (1) represent different levels of detail and allow progressive decoding; (2) support both encoder-decoder inference and decoder-only latent optimization, and fulfill multiple applications; (3) perform detailed decoder-only shape completion.

SofGAN: A Portrait Image Generator with Dynamic Styling

1 code implementation7 Jul 2020 Anpei Chen, Ruiyang Liu, Ling Xie, Zhang Chen, Hao Su, Jingyi Yu

To address this issue, we propose a SofGAN image generator to decouple the latent space of portraits into two subspaces: a geometry space and a texture space.

A Neural Rendering Framework for Free-Viewpoint Relighting

2 code implementations CVPR 2020 Zhang Chen, Anpei Chen, Guli Zhang, Chengyuan Wang, Yu Ji, Kiriakos N. Kutulakos, Jingyi Yu

We present a novel Relightable Neural Renderer (RNR) for simultaneous view synthesis and relighting using multi-view image inputs.

3D Face Reconstruction Using Color Photometric Stereo with Uncalibrated Near Point Lights

no code implementations4 Apr 2019 Zhang Chen, Yu Ji, Mingyuan Zhou, Sing Bing Kang, Jingyi Yu

We avoid the need for spatial constancy of albedo; instead, we use a new measure for albedo similarity that is based on the albedo norm profile.

Photo-Realistic Facial Details Synthesis from Single Image

1 code implementation ICCV 2019 Anpei Chen, Zhang Chen, Guli Zhang, Ziheng Zhang, Kenny Mitchell, Jingyi Yu

Our technique employs expression analysis for proxy face geometry generation and combines supervised and unsupervised learning for facial detail synthesis.

Sparse Photometric 3D Face Reconstruction Guided by Morphable Models

no code implementations CVPR 2018 Xuan Cao, Zhang Chen, Anpei Chen, Xin Chen, Cen Wang, Jingyi Yu

We present a novel 3D face reconstruction technique that leverages sparse photometric stereo (PS) and latest advances on face registration/modeling from a single image.

Deep Eyes: Binocular Depth-from-Focus on Focal Stack Pairs

no code implementations29 Nov 2017 Xinqing Guo, Zhang Chen, Siyuan Li, Yang Yang, Jingyi Yu

We then construct three individual networks: a Focus-Net to extract depth from a single focal stack, a EDoF-Net to obtain the extended depth of field (EDoF) image from the focal stack, and a Stereo-Net to conduct stereo matching.
