Handwritten Braille character recognition presents a significant challenge in the field of assistive technology, especially with the inclusion of various linguistic scripts such as Kannada. The data set is uniquely curated, combining ground-truth data from Kaggle and real-world samples collected from blind schools, segmented into vowels and consonants. The proposed system demonstrates exceptional performance in feature extraction, classification accuracy, and addressing spatial misalignments in Braille dots. Comparative analysis against state-of-the-art methods confirms the efficiency of the proposed model in overcoming the limitations of conventional techniques. The system was trained with two train test splits 70:30 and 80:20. The initial train test split has achieved 97.9 % and the latter one has achieved 98.7 %. This study aims to contribute significantly to the empowerment of visually impaired communities through advancements in automated Braille recognition systems.•The study addresses the challenge of handwritten Kannada Braille recognition using a uniquely curated dataset from Kaggle and blind schools, divided into vowels and consonants.•The proposed system achieves high accuracy (97.9 % for 70:30 and 98.7 % for 80:20 split) showing superior feature extraction and handling of spatial misalignments in Braille dots.•Comparative analysis of state-of-the-art methods confirms the model's efficiency in overcoming limitations of conventional techniques, contributing to assistive technology for visually impaired communities.
手写盲文字符识别在辅助技术领域面临重大挑战,尤其是在包含各种语言文字(如卡纳达语)的情况下。该数据集经过独特策划,结合了来自Kaggle的真实数据和从盲人学校收集的真实世界样本,并按元音和辅音进行了分割。所提出的系统在特征提取、分类准确率以及解决盲文点的空间错位方面表现出色。与最先进方法的对比分析证实了所提模型在克服传统技术局限性方面的有效性。该系统使用70:30和80:20两种训练测试分割进行训练。最初的训练测试分割达到了97.9%,后者达到了98.7%。本研究旨在通过自动盲文识别系统的进步,为视障群体的赋权做出重大贡献。
