I assume you want to convert the text that you see in the image into ASCII or Unicode text. This is called Optical Character Recognition, or OCR. Thousands of people have been working on OCR for ages. No one here is an expert on OCR and besides, it's so complicated that it's way too much to give you a tutorial or code for an OCR MATLAB package here in the Answers forum. The best we can say is to check the File Exchange for OCR, or check Vision Bib for the papers that have been written on it, or to buy a package if you just need to get the job done. For example Adobe Acrobat has OCR built in (and I'm sure they've worked many years on it) - that could be the most cost- and time-efficient way for you to convert your images.

There is no "Yes but". Your not being familiar with image processing does not somehow make Image Analyst any more familiar with Neural Networks. Image Analyst told you where to find papers on the topic, and told you where you can find some of the OCR programs that have already been implemented.
If you are having difficulty implementing an algorithm you already understand, then first consult http://www.mathworks.com/matlabcentral/answers/8026-best-way-s-to-master-matlab . Once you have some code, if you are having difficulty understanding a particular error you are encountering, then start a new Question in which you post that code and describe the error message (and which line it is occurring on.)
