Summary & Purpose
The BSU Bangla Dataset is an offline handwriting dataset of Bangla, one of the major scripts in the world. The fundamental objective of this dataset is to foster the offline Bangla handwriting text recognition related researches. The easy availability and simple structure of this dataset are believed to help the research community in developing and testing such recognizers. This dataset is an anonymous and voluntary contribution of many people and the acquisition is still going on. The development of a strong handwritten text recognizer will help to digitally store handwritten archived literature, documents and contribute in digital life automation in many ways such as digital character conversion, meaning translation, content-based image retrieval, keyword spotting, signboard translation, text-to-speech conversion, scene image analysis, postal sorting, etc.
Date of Publication or Submission
Users are free to share, copy, distribute and use the dataset; to create or produce works from the dataset; to adapt, modify, transform and build upon the dataset as long as the user attributes any public use of the dataset, or works produced from the dataset, referencing the author(s) and DOI link. For any use or redistribution of the dataset, or works produced from it, the user must make clear to others the license of the dataset and keep intact any notices on the original dataset. If users publicly use any adapted version of this dataset, or works produced from an adapted dataset, you must also offer that adapted database under this license. If users redistribute the dataset, or an adapted version of it, then users may use technological measures that restrict the work (such as DRM) as long as users also redistribute a version without such measures. This dataset may not be used for commercial purposes. If interested in commercial licensing, contact (208) 426-5765.
This research is supported by a Graduate Assistantship, awarded to Nishatul Majid, funded by the Graduate College at Boise State University through the Department of Electrical and Computer Engineering.

This is an open access dataset. For Camera and Scan folders participants of different ages and professions provided two types of handwritten documents, namely type ‘a’ and type ‘b’. The only difference between the content of the Camera and Scan folders is in how the content was captured. Type ‘a’ is an essay consisting 104 words/364 characters. This essay was carefully prepared using mostly common and frequently used Bangla words. This contains all the Bangla basic characters (except for “nio” which rarely appears in its basic form), all vowel diacritics and 32 high frequency consonant conjuncts. The type ‘b’ is a page containing isolated characters consisting all 50 basic characters, 10 numbers, all 11 vowel diacritics (with the consonant “ma”) and 10 high frequency conjuncts. For the Conjunct folder we have a collection of words which contain the most used conjuncts in Bangla language. The target content was provided in machine printed form. Contributors copied both the essay and the isolated units on blank paper. These were digitized using cellphone cameras. The images were cropped and basic skew correction was applied. No color alteration, resizing or filtering was done to the images. Although the participation was anonymous, the gender, age, profession and left/right handedness information was preserved and tagged along with their writing samples. The type of pen, pencil, paper or the photographing device was not specified. The essay images were tagged with ground truth information. All characters, words and lines are tagged with a bounding box represented with xmin , ymin , height and width values. The same was done with the images of the isolated characters and numbers. The tagged metadata were saved in plain text (*.txt) format.
