Image <strong>pre</strong>processing for optical character<br />
Abstract<br />
recognition using neural networks<br />
Author: Miroslav NOHAJ, jookie@szm.sk<br />
Supervisor: Rudolf JAKŠA, jaksa@neuron.tuke.sk<br />
Primary task of this master’s thesis is to create a theoretical and practical<br />
basis of <strong>pre</strong>processing of printed text for optical character recognition using<br />
forward-feed neural networks. Demonstration application was created and its<br />
parameters were set according to results of realized experiments.<br />
Project definition and task determination<br />
1. Write a introduction about the problematics of optical character re-<br />
cognition of characters and the methods of image <strong>pre</strong>processing before<br />
optical character recognition.<br />
2. Design a system for image <strong>pre</strong>processing using neural networks.<br />
3. Implement the designed system and simulator of printed text.<br />
4. Realize experiments to determine the settings of the system and to<br />
compare the different approaches.<br />
5. Evaluate the realized experiments and their possible practical use.<br />
6. Write a documentation according to the supervisor’s instructions.<br />
Introduction<br />
Almost everyone who is working with computers has to input some text to the<br />
computer from the paper. There is not only one way to do that. The smartest
