MVD-HuGaS: Human Gaussians from a Single Image via 3D Human Multi-view Diffusion Prior

no code implementations11 Mar 2025 Kaiqiang Xiong, Ying Feng, Qi Zhang, Jianbo Jiao, Yang Zhao, Zhihao Liang, Huachen Gao, Ronggang Wang

We first generate multi-view images from the single reference image with an enhanced multi-view diffusion model, which is well fine-tuned on high-quality 3D human datasets to incorporate 3D geometry priors and human structure priors.

GUS-IR: Gaussian Splatting with Unified Shading for Inverse Rendering

no code implementations12 Nov 2024 Zhihao Liang, Hongdong Li, Kui Jia, Kailing Guo, Qi Zhang

Recovering the intrinsic physical attributes of a scene from images, generally termed as the inverse rendering problem, has been a central and challenging task in computer vision and computer graphics.

Analytic-Splatting: Anti-Aliased 3D Gaussian Splatting via Analytic Integration

no code implementations17 Mar 2024 Zhihao Liang, Qi Zhang, WenBo Hu, Ying Feng, Lei Zhu, Kui Jia

This is because 3DGS treats each pixel as an isolated, single point rather than as an area, causing insensitivity to changes in the footprints of pixels.

Sur2f: A Hybrid Representation for High-Quality and Efficient Surface Reconstruction from Multi-view Images

no code implementations8 Jan 2024 Zhangjin Huang, Zhihao Liang, Haojie Zhang, Yangkai Lin, Kui Jia

Technically, we learn two parallel streams of an implicit signed distance field and an explicit surrogate surface Sur2f mesh, and unify volume rendering of the implicit signed distance function (SDF) and surface rendering of the surrogate mesh with a shared, neural shader; the unified shading promotes their convergence to the same, underlying surface.

GS-IR: 3D Gaussian Splatting for Inverse Rendering

1 code implementation CVPR 2024 Zhihao Liang, Qi Zhang, Ying Feng, Ying Shan, Kui Jia

We propose GS-IR, a novel inverse rendering approach based on 3D Gaussian Splatting (GS) that leverages forward mapping volume rendering to achieve photorealistic novel view synthesis and relighting results.

VISTA: Boosting 3D Object Detection via Dual Cross-VIew SpaTial Attention

1 code implementation CVPR 2022 Shengheng Deng, Zhihao Liang, Lin Sun, Kui Jia

These multi-view methods either refine the proposals predicted from single view via fused features, or fuse the features without considering the global spatial context; their performance is limited consequently.

Instance Segmentation in 3D Scenes using Semantic Superpoint Tree Networks

1 code implementation ICCV 2021 Zhihao Liang, Zhihao LI, Songcen Xu, Mingkui Tan, Kui Jia

State-of-the-art methods largely rely on a general pipeline that first learns point-wise features discriminative at semantic and instance levels, followed by a separate step of point grouping for proposing object instances.

TAG : Type Auxiliary Guiding for Code Comment Generation

no code implementations ACL 2020 Ruichu Cai, Zhihao Liang, Boyan Xu, Zijian Li, Yuexing Hao, Yao Chen

Existing leading code comment generation approaches with the structure-to-sequence framework ignores the type information of the interpretation of the code, e. g., operator, string, etc.

FGN: Fully Guided Network for Few-Shot Instance Segmentation

no code implementations CVPR 2020 Zhibo Fan, Jin-Gang Yu, Zhihao Liang, Jiarong Ou, Changxin Gao, Gui-Song Xia, Yuanqing Li

Few-shot instance segmentation (FSIS) conjoins the few-shot learning paradigm with general instance segmentation, which provides a possible way of tackling instance segmentation in the lack of abundant labeled data for training.
