Braille image recognition aims to automatically detect\nBraille dots in the whole Braille image. There is no available public datasets\nfor Braille image recognition to push relevant research and evaluate\nalgorithms. This paper constructs a large-scale Double-Sided Braille Image\ndataset DSBI with detailed Braille recto dots, verso dots and Braille cells\nannotation. To quickly annotate Braille images, an auxiliary annotation\nstrategy is proposed, which adopts initial automatic detection of Braille dots\nand modifies annotation results by convenient human-computer interaction\nmethod. This labeling strategy can averagely increase label efficiency by six\ntimes for recto dots annotation in one Braille image. Braille dots detection is\nthe core and basic step for Braille image recognition. This paper also\nevaluates some Braille dots detection methods on our dataset DSBI and gives the\nbenchmark performance of recto dots detection. We have released our Braille\nimages dataset on the GitHub website.","url_abs":"http://arxiv.org/abs/1811.10893v2","url_pdf":"http://arxiv.org/pdf/1811.10893v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"dsbi-double-sided-braille-image-dataset-and","repo_url":"https://github.com/yeluo1994/DSBI","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[{"slug":"dsbi","name":"DSBI","full_name":"Double-Sided Braille Image"}],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
