However, scene text detection presents a formidable challenge in real-world scenarios, given the complexities arising from diverse backgrounds, text styles, irregular arrangements, and image blurriness. In this research, we propose a scene text detection system. In this system, we introduce ConvNeXt V2 Tiny as the backbone architecture, with the aim of enhancing performance. Additionally, we introduce attention mechanisms, incorporate normalization methods, and modify activation functions to improve accuracy and training stability. In our experiments, our system is evaluated on three public datasets: MSRA-TD500, Total-Text, and SCUT-CTW1500. Each of these datasets is used to assess the performance of the model in different types of text regions. The experimental results indicate that our system has shown a notable improvement in performance compared to the baseline model and outperforms the SOTA system with fewer parameters. en_US DC.subject 場景文字檢測 zh_TW DC.subject 深度學習 zh_TW DC.subject 注意力機制 zh_TW DC.subject Scene Text Detection en_US DC.subject deep learning en_US DC.subject attention en_US DC.title Scene Text Detection Based on Attention ConvNeXt en_US dc.language.iso en_US en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
