We present a new modular traffic signs recognition system, successfully applied to both American and European speed limit signs. Our sign detection step is based only on shape-detection (rectangles or circles). This enables it to work on grayscale images, contrary to most European competitors, which eases robustness to illumination conditions (notably night operation). Speed sign candidates are...

TSR (Traffic sign recognition) is an important problem in ITS (intelligent traffic system), which is being paid more and more attention for realizing drivers assisting system and unmanned vehicle etc. TSR consists of two steps: detection and recognition, and this paper describe a new traffic sign detection method. The design principle of the traffic sign is comply with the visual attention mech...

This paper is focused on an evaluation of quality of synthesized sign speech and a comparison of sign and visual speech. The evaluation has been performed with the Czech sign speech synthesis system. The system produces a manual component as well as a non-manual component given by the lip articulation. The perception test by deaf children from primary school is scored on the isolated signs. Two...

Vision therapy is prescribed to treat diagnosed conditions of the visual system. Effective therapy requires visual skills to be developed until they are integrated with other systems and become automatic, enabling individuals to achieve their full potential. The goals of a prescribed vision therapy treatment regimen are to achieve desired visual outcomes, alleviate the signs and symptoms, meet ...

To assess inapparent visual field defects in patients with multiple sclerosis free from optic neuritis. During 5 years period 120 patients with multiple sclerosis were examined at the University Department of Ophthalmology, Zagreb University Hospital Center. They were divided into three groups with 40 patients each: patients with acute unilateral optic neuritis, referred to ophthalmologist and ...

Background Preterm infants have a high risk to develop visual deficits due to retinopathy of prematurity (ROP), brain lesionsand prematurity per se [1]. The possibility to assess different aspects of visual function can allow early and specific intervention in an attempt to reduce the risk of difficulties in motor coordination, attention and learning at school age. The aim is to identify early ...
