Pre-Processing of Mobile Camera Captured Images for OCR

Optical Character Recognition (OCR) systems are nowadays capable of recognizing different printed scripts but the accuracy of any OCR system mainly depends upon the quality of text image. Mobile phones have become the most popular handheld device in this era of technology. A new way to digitize the image is using the mobile camera. Although it is very easy to capture the image with mobile camera but it also brings a lot of challenges. Various challenges in mobile camera captured images are discussed in this paper. Various pre-processing operations need to be performed on the camera captured input image to enhance its quality. This paper also presents the implementation of different pre-processing techniques to improve the quality of camera captured image which can be further used in text recognition. &nbsp
