Deep learning based hand written character recognition for manuscript documents

Abstract

Handwritten manuscripts contain much ancient information related to astrology, medicines, grammar etc. They are of various forms such as palm leaves, paper, stones etc. These manuscripts are preserved by the method of digitization with noise introduced. By using proper filtering as well as denoising methods these noises are eliminated and the images are restored. It is finally required to recognize the handwritten characters automatically from the restored image enabling the researchers and enthusiasts for going through the document very easily.This proposed work deals with the creation of handwritten characters dataset for all the characters within a specific dimensional area and recognition of handwritten characters using deep learning method. First the handwritten dataset is created from different human handwritings in a specific format, scanned and each character with suitable dimension is obtained by labeling them as per sequence. Then various forms of convolution network are applied for the character recognition and the results are compared to obtain the suitable net for the Tamil character recognition from the handwritten document.
