Natural Scene Braille Character Recognition Dataset

There are a total of 1157 Braille segment images in this dataset, including 925 in the training set and 232 in the testing set. There are two folders in the directory of this dataset: character_label and segment_label. The character_rabel file contains three formats of Braille segment images: (1) Braille segment images and label files stored in ICDAR-2015 format, each. jpg file corresponds to a. txt file, where each line stores the position and recognition label of a braille character rectangle box. The data corresponds to the coordinates of the four points in the rectangle box and the recognized numerical label; (2) The original format of the data is stored in the folder org. Each .jpg file in this folder corresponds to a .json file which marked by labelme software; (3) VOC format, stored in voc-data folder. This folder stores images and corresponding .xml files in VOC format, and marks the position of each braille character rectangle box and its corresponding numerical label information in the .xml file. In addition, the original Braille images of natural scenes and the corresponding Braille segment markings .json files are stored in the folder segment_label.
