Aerial Lifting: Neural Urban Semantic and Building Instance Lifting from Aerial Imagery

1 code implementation18 Mar 2024 Yuqi Zhang, GuanYing Chen, Jiaxing Chen, Shuguang Cui

We then introduce a novel cross-view instance label grouping strategy based on the 3D scene representation to mitigate the multi-view inconsistency problem in the 2D instance labels.

Efficient Large-scale Scene Representation with a Hybrid of High-resolution Grid and Plane Features

1 code implementation6 Mar 2023 Yuqi Zhang, GuanYing Chen, Shuguang Cui

Based on this hybrid representation, we propose a fast optimization NeRF variant, called GP-NeRF, that achieves better rendering results while maintaining a compact model size.

NeuralMPS: Non-Lambertian Multispectral Photometric Stereo via Spectral Reflectance Decomposition

no code implementations28 Nov 2022 Jipeng Lv, Heng Guo, GuanYing Chen, Jinxiu Liang, Boxin Shi

S$^3$-NeRF: Neural Reflectance Field from Shading and Shadow under a Single Viewpoint

no code implementations17 Oct 2022 Wenqi Yang, GuanYing Chen, Chaofeng Chen, Zhenfang Chen, Kwan-Yee K. Wong

Different from existing single-view methods which can only recover a 2. 5D scene representation (i. e., a normal / depth map for the visible surface), our method learns a neural reflectance field to represent the 3D geometry and BRDFs of a scene.
