Frozen Transformers in Language Models Are Effective Visual Encoder Layers

2 code implementations19 Oct 2023 Ziqi Pang, Ziyang Xie, Yunze Man, Yu-Xiong Wang

This paper reveals that large language models (LLMs), despite being trained solely on textual data, are surprisingly strong encoders for purely visual tasks in the absence of language.

MV-Map: Offboard HD-Map Generation with Multi-view Consistency

1 code implementation ICCV 2023 Ziyang Xie, Ziqi Pang, Yu-Xiong Wang

To further enhance multi-view consistency, we augment the uncertainty network with the global 3D structure optimized by a voxelized neural radiance field (Voxel-NeRF).

S-NeRF: Neural Radiance Fields for Street Views

no code implementations1 Mar 2023 Ziyang Xie, Junge Zhang, Wenye Li, Feihu Zhang, Li Zhang

Specifically, we improve the scene parameterization function and the camera poses for learning better neural representations from street views.
