Relationship between night myopia and night-time motor vehicle accidents.

PURPOSE To investigate the relationship between night myopia and the occurrence of night-time motor vehicle accidents in a group of professional drivers. METHODS We examined 136 professional drivers.

The vehicle identification has been carried out using the headlights, which may be the only key feature available to identify vehicles under low light conditions through visible light. Due to lack of features, the veh...

Because of the camera movement, background frames are not available and must be ”localized“ in former sequences and registered with the current frames. To this end, we propose a Frame Localization And Registration (FLAR) approach t...
