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)
PURPOSE The aim of the investigations was to state whether strabismic amblyopia and aniseiconia can be connected with disturbance of visual evoked potentials (VEP). MATERIAL AND METHODS VEP investigations in 28 children with amblyopia, aged from 4 to 12 years and in 16 healthy persons were performed. Analysis of amplitude and latency of the positive wave(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)
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)
