  Language is a method by which individuals express their thoughts. Each
language has its own set of alphabetic and numeric characters. People can
communicate with one another through either oral or written communication.
However, each language has a sign language counterpart. Individuals who are
deaf and/or mute communicate through sign language. The Bangla language also
has a sign language, which is called BDSL. The dataset is about Bangla hand
sign images. The collection contains 49 individual Bangla alphabet images in
sign language. BDSL49 is a dataset that consists of 29,490 images with 49
labels. Images of 14 different adult individuals, each with a distinct
background and appearance, have been recorded during data collection. Several
strategies have been used to eliminate noise from datasets during preparation.
This dataset is available to researchers for free. They can develop automated
systems using machine learning, computer vision, and deep learning techniques.
In addition, two models were used in this dataset. The first is for detection,
while the second is for recognition.
