Frozen Transformers in Language Models Are Effective Visual Encoder Layers

1 code implementation19 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.

Streaming Motion Forecasting for Autonomous Driving

1 code implementation2 Oct 2023 Ziqi Pang, Deva Ramanan, Mengtian Li, Yu-Xiong Wang

Our benchmark inherently captures the disappearance and re-appearance of agents, presenting the emergent challenge of forecasting for occluded agents, which is a safety-critical problem yet overlooked by snapshot-based benchmarks.

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).

Embracing Single Stride 3D Object Detector with Sparse Transformer

2 code implementations CVPR 2022 Lue Fan, Ziqi Pang, Tianyuan Zhang, Yu-Xiong Wang, Hang Zhao, Feng Wang, Naiyan Wang, Zhaoxiang Zhang

In LiDAR-based 3D object detection for autonomous driving, the ratio of the object size to input scene size is significantly smaller compared to 2D detection cases.

Immortal Tracker: Tracklet Never Dies

1 code implementation26 Nov 2021 Qitai Wang, Yuntao Chen, Ziqi Pang, Naiyan Wang, Zhaoxiang Zhang

We employ a simple Kalman filter for trajectory prediction and preserve the tracklet by prediction when the target is not visible.
