Deep3DSketch+: Rapid 3D Modeling from Single Free-hand Sketches

no code implementations22 Sep 2023 Tianrun Chen, Chenglong Fu, Ying Zang, Lanyun Zhu, Jia Zhang, Papa Mao, Lingyun Sun

In this work, we introduce a novel end-to-end approach, Deep3DSketch+, which performs 3D modeling using only a single free-hand sketch without inputting multiple sketches or view information.

PanopticNeRF-360: Panoramic 3D-to-2D Label Transfer in Urban Scenes

1 code implementation19 Sep 2023 Xiao Fu, Shangzhan Zhang, Tianrun Chen, Yichong Lu, Xiaowei Zhou, Andreas Geiger, Yiyi Liao

Moreover, PanopticNeRF-360 enables omnidirectional rendering of high-fidelity, multi-view and spatiotemporally consistent appearance, semantic and instance labels.

Learning Gabor Texture Features for Fine-Grained Recognition

no code implementations ICCV 2023 Lanyun Zhu, Tianrun Chen, Jianxiong Yin, Simon See, Jun Liu

We innovatively utilize Gabor filters as a powerful extractor to exploit texture features, motivated by the capability of Gabor filters in effectively capturing multi-frequency features and detailed local information.

Dyn-E: Local Appearance Editing of Dynamic Neural Radiance Fields

no code implementations24 Jul 2023 Shangzhan Zhang, Sida Peng, Yinji ShenTu, Qing Shuai, Tianrun Chen, Kaicheng Yu, Hujun Bao, Xiaowei Zhou

We extensively evaluate our approach on various scenes and show that our approach achieves spatially and temporally consistent editing results.

Painting 3D Nature in 2D: View Synthesis of Natural Scenes from a Single Semantic Mask

no code implementations CVPR 2023 Shangzhan Zhang, Sida Peng, Tianrun Chen, Linzhan Mou, Haotong Lin, Kaicheng Yu, Yiyi Liao, Xiaowei Zhou

We introduce a novel approach that takes a single semantic mask as input to synthesize multi-view consistent color images of natural scenes, trained with a collection of single images from the Internet.

Panoptic NeRF: 3D-to-2D Label Transfer for Panoptic Urban Scene Segmentation

1 code implementation29 Mar 2022 Xiao Fu, Shangzhan Zhang, Tianrun Chen, Yichong Lu, Lanyun Zhu, Xiaowei Zhou, Andreas Geiger, Yiyi Liao

In this work, we present a novel 3D-to-2D label transfer method, Panoptic NeRF, which aims for obtaining per-pixel 2D semantic and instance labels from easy-to-obtain coarse 3D bounding primitives.
