Abstract :
Being able to read LCD/LED displays would be a very important step towards greater independence for persons who are blind or have low vision. A fast graphical model based algorithm is proposed for reading 7-segment digits in LCD/LED displays. The algorithm is implemented for Symbian camera cell phones in Symbian C++. The software reads one display in about 2 seconds by a push of a button on the cell phone (Nokia 6681, 220 MHz ARM CPU).
