Abstract

Demands for an automatic translation based on Camera-based Multilingual Optical Character Recognition (CM-OCR) are increasing. In addition, CM-OCR methods usually employ a script identification step before character recognition. Recent approaches for script identification depend on a Convolutional Neural Networks (CNN) thanks to its promising performance in the image recognition task. However, res...
