NESI: Shape Representation via Neural Explicit Surface Intersection

no code implementations9 Sep 2024 Congyi Zhang, Jinfan Yang, Eric Hedlin, Suzuran Takikawa, Nicholas Vining, Kwang Moo Yi, Wenping Wang, Alla Sheffer

Conversely, parametric representations support the latter tasks but are ill-suited for occupancy queries.

TexPainter: Generative Mesh Texturing with Multi-view Consistency

1 code implementation17 May 2024 HongKun Zhang, Zherong Pan, Congyi Zhang, Lifeng Zhu, Xifeng Gao

Based on the celebrated Denoising Diffusion Implicit Models (DDIM) scheme, we propose to use an optimization-based color-fusion to enforce consistency and indirectly modify the latent codes by gradient back-propagation.

Skull-to-Face: Anatomy-Guided 3D Facial Reconstruction and Editing

no code implementations24 Mar 2024 Yongqing Liang, Congyi Zhang, Junli Zhao, Wenping Wang, Xin Li

Existing methods for automated facial reconstruction yield inaccurate results, suffering from the non-determinative nature of the problem that a skull with a sparse set of tissue depth cannot fully determine the skinned face.

On Optimal Sampling for Learning SDF Using MLPs Equipped with Positional Encoding

no code implementations2 Jan 2024 Guying Lin, Lei Yang, YuAn Liu, Congyi Zhang, Junhui Hou, Xiaogang Jin, Taku Komura, John Keyser, Wenping Wang

Sampling against this intrinsic frequency following the Nyquist-Sannon sampling theorem allows us to determine an appropriate training sampling rate.

An Implicit Parametric Morphable Dental Model

no code implementations21 Nov 2022 Congyi Zhang, Mohamed Elgharib, Gereon Fox, Min Gu, Christian Theobalt, Wenping Wang

Current dental models use an explicit mesh scene representation and model only the teeth, ignoring the gum.

Batch-based Model Registration for Fast 3D Sherd Reconstruction

no code implementations ICCV 2023 Jiepeng Wang, Congyi Zhang, Peng Wang, Xin Li, Peter J. Cobb, Christian Theobalt, Wenping Wang

In this work, we aim to develop a portable, high-throughput, and accurate reconstruction system for efficient digitization of fragments excavated in archaeological sites.
