Abstract

The process of attaching a symbolic identification to a character’s visual is known as character recognition. There are numerous handwritten characters of various languages, Bengali is one of them. Detecting handwritten documents is exceedingly challenging in today’s digital age due to the vast range of uses, unique shapes, and morphologically complicated formation. Besides, people’s handwritings are identical to them and vary according to sizes, shapes, and styles. Bangla has a lot of similar-looking characters that can be confusing to anyone who is not familiar with the language. In many circumstances, a single dot or mark distinguishes one character from another. Our paper describes an approach to recognize Bangla handwritten characters based on convolutional neural network. Here, we develop a new convolutional neural network model and test our model with CMATERdb 3.1.2 dataset. Our model obtains an average training accuracy of 98.78%, average validation accuracy of 98.33%, and average test accuracy of 98.21% on the alphabets of the dataset which outperforms the performances with the existing methods in the literature. This study paves the way for further advancements in the field of Bangla handwriting recognition by offering a framework for individual character recognition.
