Efficient Decoder for End-to-End Oriented Object Detection in Remote Sensing Images

no code implementations29 Nov 2023 Jiaqi Zhao, Zeyu Ding, Yong Zhou, Hancheng Zhu, Wenliang Du, Rui Yao, Abdulmotaleb El Saddik

To address these limitations, we propose an end-to-end oriented detector equipped with an efficient decoder, which incorporates two technologies, Rotated RoI attention (RRoI attention) and Selective Distinct Queries (SDQ).

A unified framework for STAR-RIS coefficients optimization

no code implementations13 Oct 2023 Hancheng Zhu, Yuanwei Liu, Yik Chung Wu, Vincent K. N. Lau

Due to the lack of a unified comparison of communication systems equipped with different modes of STAR-RIS and the performance degradation caused by the constraints involving discrete selection, this paper proposes a unified optimization framework for handling the STAR-RIS operating mode and discrete phase constraints.

CT-Net: Arbitrary-Shaped Text Detection via Contour Transformer

no code implementations25 Jul 2023 Zhiwen Shao, Yuchen Su, Yong Zhou, Fanrong Meng, Hancheng Zhu, Bing Liu, Rui Yao

Contour based scene text detection methods have rapidly developed recently, but still suffer from inaccurate frontend contour initialization, multi-stage error accumulation, or deficient local information aggregation.

TextDCT: Arbitrary-Shaped Text Detection via Discrete Cosine Transform Mask

no code implementations27 Jun 2022 Yuchen Su, Zhiwen Shao, Yong Zhou, Fanrong Meng, Hancheng Zhu, Bing Liu, Rui Yao

Arbitrary-shaped scene text detection is a challenging task due to the variety of text changes in font, size, color, and orientation.

Generalizable No-Reference Image Quality Assessment via Deep Meta-learning

1 code implementation IEEE Transactions on Circuits and Systems for Video Technology 2021 Hancheng Zhu, Leida Li, Jinjian Wu, Weisheng Dong, and Guangming Shi

Based on these two task sets, an optimization-based meta-learning is proposed to learn the generalized NR-IQA model, which can be directly used to evaluate the quality of images with unseen distortions.

MetaIQA: Deep Meta-learning for No-Reference Image Quality Assessment

1 code implementation CVPR 2020 Hancheng Zhu, Leida Li, Jinjian Wu, Weisheng Dong, Guangming Shi

The underlying idea is to learn the meta-knowledge shared by human when evaluating the quality of images with various distortions, which can then be adapted to unknown distortions easily.

Facial Action Unit Detection via Adaptive Attention and Relation

no code implementations5 Jan 2020 Zhiwen Shao, Yong Zhou, Jianfei Cai, Hancheng Zhu, Rui Yao

Specifically, we propose an adaptive attention regression network to regress the global attention map of each AU under the constraint of attention predefinition and the guidance of AU detection, which is beneficial for capturing both specified dependencies by landmarks in strongly correlated regions and facial globally distributed dependencies in weakly correlated regions.
