Title Restoring Turbulence-Degraded Underwater Images.
Publication Date Nov 2012
Media Count 4p
Personal Author A. Kanaev W. Hou
Abstract Underwater imaging is essential for a variety of scientific and military applications, such as optical communications, situational awareness, diver visibility, and mine detection. Unfortunately underwater imaging is severely impaired by scattering and optical turbulence associated with refraction index fluctuations. Because of the similarities between underwater and atmospheric image degradation, approaches taken to solve the underwater image restoration problem originate in atmospheric turbulence compensation algorithms. However, applying unmodified atmospheric techniques to underwater images fails because of the differences in the scale of the refraction index fluctuations.
