Zpracování zvukového signálu na počítači

Abstract

In my thesis I deal with problems of optical character recognition. The final application consists of two parts. The first part is solved by the transfer of text from an image file to a normal text and in the second part the text is converted into audio form. The application uses freeware Asprise OCR for conversion to a text and for audio section it uses an application from the Bachelor thesis of Mr. Brettšnajdr. Solution of this thesis is divided into several tasks within a single unit so that this particular application could serve especially visually impaired people who cannot efficiently obtain text information due to their disability. This thesis also deals with jpeg format and marginally introduces the work with the graphical user interface in Java.
