ZiNet: Linking Chinese Characters Spanning Three Thousand Years

1 code implementation Findings (ACL) 2022 Yang Chi, Fausto Giunchiglia, Daqian Shi, Xiaolei Diao, Chuntao Li, Hao Xu

In addition, powered by the knowledge of radical systems in ZiNet, this paper introduces glyph similarity measurement between ancient Chinese characters, which could capture similar glyph pairs that are potentially related in origins or semantics.

Toward Zero-shot Character Recognition: A Gold Standard Dataset with Radical-level Annotations

no code implementations1 Aug 2023 Xiaolei Diao, Daqian Shi, Jian Li, Lida Shi, Mingzhe Yue, Ruihua Qi, Chuntao Li, Hao Xu

To increase the adaptability of ACCID, we propose a splicing-based synthetic character algorithm to augment the training samples and apply an image denoising method to improve the image quality.

Incremental Image Labeling via Iterative Refinement

no code implementations18 Apr 2023 Fausto Giunchiglia, Xiaolei Diao, Mayukh Bagchi

Data quality is critical for multimedia tasks, while various types of systematic flaws are found in image benchmark datasets, as discussed in recent work.

FCC: Feature Clusters Compression for Long-Tailed Visual Recognition

1 code implementation CVPR 2023 Jian Li, Ziyao Meng, Daqian Shi, Rui Song, Xiaolei Diao, Jingwen Wang, Hao Xu

Through representation learning, DNNs can map BFs into dense clusters in feature space, while the features of minority classes often show sparse clusters.

Aligning Visual and Lexical Semantics

no code implementations13 Dec 2022 Fausto Giunchiglia, Mayukh Bagchi, Xiaolei Diao

We discuss two kinds of semantics relevant to Computer Vision (CV) systems - Visual Semantics and Lexical Semantics.

CharFormer: A Glyph Fusion based Attentive Framework for High-precision Character Image Denoising

1 code implementation16 Jul 2022 Daqian Shi, Xiaolei Diao, Lida Shi, Hao Tang, Yang Chi, Chuntao Li, Hao Xu

Degraded images commonly exist in the general sources of character images, leading to unsatisfactory character recognition results.

RZCR: Zero-shot Character Recognition via Radical-based Reasoning

no code implementations12 Jul 2022 Xiaolei Diao, Daqian Shi, Hao Tang, Qiang Shen, Yanzeng Li, Lei Wu, Hao Xu

The long-tail effect is a common issue that limits the performance of deep learning models on real-world datasets.

Building a visual semantics aware object hierarchy

no code implementations26 Feb 2022 Xiaolei Diao

To address this problem, we propose a novel unsupervised method to build visual semantics aware object hierarchy, aiming to get a classification model by learning from pure-visual information and to dissipate the bias of linguistic representations caused by SGP.
