Researchers at China's Tianjin University have devised a methodology that automatically generates clear images through murky water.
The new process combines a traditional polarized imaging framework with an algorithm that automatically identifies the optimal parameters to suppress the scattering of light by particles clouding the water.
Said Tianjin's Haofeng Hu, "Our experimental results show that our method has distinct advantages in terms of suppressing scattering, recovering details and reducing noise when imaging different objects in water with various turbidities.
"While background regions are often not visible in dense turbid water, our method was able to accomplish clear vision in this environment.”
