Non-Visible Light Data Synthesis and Application: A Case Study for Synthetic Aperture Radar Imagery

no code implementations29 Nov 2023 Zichen Tian, Zhaozheng Chen, Qianru Sun

If large-scale models pre-trained with regular images can be adapted to generating novel SAR images, the problem is solved.

Domain Adaptive Scene Text Detection via Subcategorization

no code implementations1 Dec 2022 Zichen Tian, Chuhui Xue, Jingyi Zhang, Shijian Lu

We study domain adaptive scene text detection, a largely neglected yet very meaningful task that aims for optimal transfer of labelled scene text images while handling unlabelled images in various new domains.

Towards Efficient Use of Multi-Scale Features in Transformer-Based Object Detectors

no code implementations CVPR 2023 Gongjie Zhang, Zhipeng Luo, Zichen Tian, Jingyi Zhang, Xiaoqin Zhang, Shijian Lu

Multi-scale features have been proven highly effective for object detection but often come with huge and even prohibitive extra computation costs, especially for the recent Transformer-based detectors.

Fourier Document Restoration for Robust Document Dewarping and Recognition

1 code implementation CVPR 2022 Chuhui Xue, Zichen Tian, Fangneng Zhan, Shijian Lu, Song Bai

State-of-the-art document dewarping techniques learn to predict 3-dimensional information of documents which are prone to errors while dealing with documents with irregular distortions or large variations in depth.

Spectral Unsupervised Domain Adaptation for Visual Recognition

no code implementations CVPR 2022 Jingyi Zhang, Jiaxing Huang, Zichen Tian, Shijian Lu

Second, it introduces multi-view spectral learning that learns useful unsupervised representations by maximizing mutual information among multiple ST-generated spectral views of each target sample.
