VOCABULARY-INFORMED VISUAL FEATURE AUGMENTATION FOR ONE-SHOT LEARNING

no code implementations ICLR 2018 jianqi ma, Hangyu Lin, yinda zhang, Yanwei Fu, xiangyang xue

Besides directly augmenting image features, we transform the image features to semantic space using the encoder and perform the data augmentation.

RRPN++: Guidance Towards More Accurate Scene Text Detection

1 code implementation28 Sep 2020 Jianqi Ma

In inference stage, the detection branch outputs the proposal refinement and the recognition branch predicts the transcript of the refined text region.

Text Prior Guided Scene Text Image Super-resolution

1 code implementation29 Jun 2021 jianqi ma, Shi Guo, Lei Zhang

Our experiments on the benchmark TextZoom dataset show that TPGSR can not only effectively improve the visual quality of scene text images, but also significantly improve the text recognition accuracy over existing STISR methods.

Benchmarking Chinese Text Recognition: Datasets, Baselines, and an Empirical Study

1 code implementation30 Dec 2021 Haiyang Yu, Jingye Chen, Bin Li, jianqi ma, Mengnan Guan, Xixi Xu, Xiaocong Wang, Shaobo Qu, xiangyang xue

The experimental results indicate that the performance of baselines on CTR datasets is not as good as that on English datasets due to the characteristics of Chinese texts that are quite different from the Latin alphabet.

BTS: A Bi-Lingual Benchmark for Text Segmentation in the Wild

no code implementations CVPR 2022 Xixi Xu, Zhongang Qi, jianqi ma, Honglun Zhang, Ying Shan, XiaoHu Qie

Current researches mainly focus on only English characters and digits, while few work studies Chinese characters due to the lack of public large-scale and high-quality Chinese datasets, which limits the practical application scenarios of text segmentation.

Spatial-Frequency Attention for Image Denoising

no code implementations27 Feb 2023 Shi Guo, Hongwei Yong, Xindong Zhang, jianqi ma, Lei Zhang

In this paper, we propose the spatial-frequency attention network (SFANet) to enhance the network's ability in exploiting long-range dependency.

A Benchmark for Chinese-English Scene Text Image Super-resolution

1 code implementation ICCV 2023 jianqi ma, Zhetong Liang, Wangmeng Xiang, Xi Yang, Lei Zhang

Scene Text Image Super-resolution (STISR) aims to recover high-resolution (HR) scene text images with visually pleasant and readable text content from the given low-resolution (LR) input.

Motion-Guided Latent Diffusion for Temporally Consistent Real-world Video Super-resolution

1 code implementation1 Dec 2023 Xi Yang, Chenhang He, jianqi ma, Lei Zhang

To ensure the content consistency among adjacent frames, we exploit the temporal dynamics in LR videos to guide the diffusion process by optimizing the latent sampling path with a motion-guided loss, ensuring that the generated HR video maintains a coherent and continuous visual flow.

Toward Accurate and Temporally Consistent Video Restoration from Raw Data

1 code implementation25 Dec 2023 Shi Guo, jianqi ma, Xi Yang, Zhengqiang Zhang, Lei Zhang

Extensive experiments demonstrate the leading VJDD performance of our method in term of restoration accuracy, perceptual quality and temporal consistency.
