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.

Improving the Generalization of Segmentation Foundation Model under Distribution Shift via Weakly Supervised Adaptation

1 code implementation6 Dec 2023 Haojie Zhang, Yongyi Su, Xun Xu, Kui Jia

The success of large language models has inspired the computer vision community to explore image segmentation foundation model that is able to zero/few-shot generalize through prompt engineering.

Better Pre-Training by Reducing Representation Confusion

no code implementations9 Oct 2022 Haojie Zhang, Mingfei Liang, Ruobing Xie, Zhenlong Sun, Bo Zhang, Leyu Lin

Motivated by the above investigation, we propose two novel techniques to improve pre-trained language models: Decoupled Directional Relative Position (DDRP) encoding and MTH pre-training objective.
