Enlighten-Your-Voice: When Multimodal Meets Zero-shot Low-light Image Enhancement

1 code implementation15 Dec 2023 Xiaofeng Zhang, Zishan Xu, Hao Tang, Chaochen Gu, Wei Chen, Shanying Zhu, Xinping Guan

Low-light image enhancement is a crucial visual task, and many unsupervised methods tend to overlook the degradation of visible information in low-light scenes, which adversely affects the fusion of complementary information and hinders the generation of satisfactory results.

SAM-helps-Shadow:When Segment Anything Model meet shadow removal

1 code implementation1 Jun 2023 Xiaofeng Zhang, Chaochen Gu, Shanying Zhu

The challenges surrounding the application of image shadow removal to real-world images and not just constrained datasets like ISTD/SRD have highlighted an urgent need for zero-shot learning in this field.

Distribution Learning Based on Evolutionary Algorithm Assisted Deep Neural Networks for Imbalanced Image Classification

no code implementations26 Jul 2022 Yudi Zhao, Kuangrong Hao, Chaochen Gu, Bing Wei

To address the trade-off problem of quality-diversity for the generated images in imbalanced classification tasks, we research on over-sampling based methods at the feature level instead of the data level and focus on searching the latent feature space for optimal distributions.

Self-supervised Implicit Glyph Attention for Text Recognition

1 code implementation CVPR 2023 Tongkun Guan, Chaochen Gu, Jingzheng Tu, Xue Yang, Qi Feng, Yudi Zhao, Xiaokang Yang, Wei Shen

Supervised attention can alleviate the above issue, but it is character category-specific, which requires extra laborious character-level bounding box annotations and would be memory-intensive when handling languages with larger character categories.

Complementary Patch for Weakly Supervised Semantic Segmentation

1 code implementation ICCV 2021 Fei Zhang, Chaochen Gu, Chenyue Zhang, Yuchao Dai

Therefore, a CAM with more information related to object seeds can be obtained by narrowing down the gap between the sum of CAMs generated by the CP Pair and the original CAM.
