Character recognition system for cellular phone with camera

Abstract

This paper describes camera based character recognition system, which is implemented for mobile devices such as PDA and cellular phones with color cameras. First, we have developed camera based character recognition system for PC that includes techniques such as image enhancement, local adaptive binarization and blob coloring to effectively extract character region and remove the noise of camera captured images. Then, we converted the PC based OCR system to the embedded OCR system for cellular phones. Several functions were specially developed since most of mobile telecommunication devices have no real number computing functions and have limitation of memory space. In this paper, we are addressing the related problems and our system mechanisms.
