| Περίληψη | Underwater imaging is important for scientific research and technology, as well as for popular activities. This paper describes a method to overcome limitations in underwater imaging using colour correction and polarizing filters. Scattering and colour absorption are two major problems of distortion for imaging, especially in underwater environment. Scattering is caused by large suspended particles, like fog or turbid water. Colour degradation corresponds to the varying degrees of attenuation encountered by light travelling in the water with different wavelengths, rendering ambient underwater environments dominated by a bluish tone. Our key target was to create a simple and cost efficient method eliminating satisfactorily image blurring and increase colour intensity and visual acuity in natural an artificial lighting source. We demonstrated light as a signal with scattering and backscattering distorting images and also analyzed the function of the human eye contributing to the constraints of vision especially in underwater environment. We researched various different approaches encounter the same topic and made a comparative study and developed an underwater vision system which improves contrast and visual image quality and explained the physical effects of visibility degradation. | en |
