Abstract
Embedded products have different types of display screens like LCD, Touch screen, CRT etc. For automating the development testing of such devices, we need to recognize the text displayed on it using a camera. It is always a challenge to recognize the LCD display screen using OCR engines. Due to the custom display nature of these LCD controllers as well as the small font size, character recognition is a complex job. Traditional way of recognizing such screens uses template matching techniques. Such image matching techniques take precious time which drastically increases depending upon the number of characters and their size. In this paper, we are going to discuss an algorithm, which helps to recognize such small text in an accurate and speedy manner using low cost resources like webcam and open source software.
