The system capable of localizing and reading aloud text embedded in natural scene images can be very helpful for blind and visually impaired persons - providing information useful in everyday life, it increases their confidence and autonomy. Even though the currently available optical character recognition (OCR) programs are fast and accurate, most of them(More)
The paper presents results of the work concerning the technical specification of Immersive 3D Visualization Laboratory to be opened in late summer 2014 at the Faculty of Electronics, Telecommunications and Informatics at Gdańsk University of Technology in Poland. The person immersed in VR space will be placed in a transparent sphere with a diameter of over(More)
This paper describes the modern Immersive 3D Visualization Lab (I3DVL) established at the Faculty of Electronics, Telecommunications and Informatics of the Gdańsk University of Technology (GUT) and its potential to prepare virtual tours and architectural visualizations on the example of the application allowing a virtual walk through the Coal Market(More)
In the paper an advanced concept for a Virtual Reality (VR) CAVE installation is presented, which should allow for human immersion in a spatially unlimited virtual world. The CAVE will be completed by the end of 2013 in a special building designed and constructed for the purpose. The unit will simulate an autonomous movement of a human inside a computer(More)

A system dedicated to visually impaired persons for revealing and reading aloud text may use standard optical character recognition (OCR) component. However the OCR component cannot analyze directly photographs taken out of doors in towns because of their complexity. Before launching the OCR component the photos require preprocessing that may relay on image(More)
