BanglaLekha-Isolated

This dataset, BanglaLekha-Isolated, is a collection of Bangla handwritten isolated character samples . It contains samples of 50 Bangla basic characters, 10 Bangla numerals and 24 selected compound characters. 2000 handwriting samples for each of the 84 characters were collected, digitized and pre-processed. After discarding mistakes and scribbles, 1,66,105 handwritten character images were included in the final dataset. The dataset also includes information about the age and gender of the subjects from whom the handwriting samples were collected. This information is mapped to each individual image. A separate spreadsheet gives an assessment of the aesthetic quality of the handwriting samples, collected from three independent assessors. This assessment is done on groups of 84 characters and not on individual characters.

本数据集为BanglaLekha-Isolated（孟加拉语手写孤立字符数据集），系孟加拉语手写孤立字符样本的集合。其涵盖50个孟加拉语基础字符、10个孟加拉语数字以及24个精选复合字符的样本。研究人员为该84类字符各收集了2000份手写样本，并完成了数字化与预处理流程。经剔除错误样本与涂鸦笔迹后，最终数据集共收录166105张手写字符图像。本数据集同时附带手写样本提供者的年龄与性别信息，且该信息与每一张独立图像一一对应绑定。另有一份独立电子表格，记录了由三位独立评估人员给出的手写样本美学质量评估结果，该评估以84类字符为一组开展，而非针对单个字符进行。
