OFF-LINE HANDWRITTEN DATABASE FOR BANGLA BASIC
CHARACTERS
Our database of Bangla handwritten basic characters consists of 20187 isolated basic character images. However, these samples are not evenly distributed over 50 possible classes. The main reason of such uneven distribution is that a major part of the data have been collected using several standard forms in which entries are proper nouns and there are several characters in the Bangla alphabet which are rarely used in proper nouns. However, this problem has been partially tackled by asking the subjects to reproduce Bangla alphabet set on a form consisting of equal rectangles, one for each basic character. We targeted to have more than 200 samples in each category. Our approach for data collection yielded several thousand samples in a few categries. But in such cases we included only 500 random samples from each of those categories into our final database.
