Abstract: |
This paper
considers methods of color underwater images simulation based on terrestrial
images. These methods avoid the expensive process of collecting real data to
develop algorithms for improving underwater images. To model light
attenuation underwater, existing works often use channel-wise approximation
of the Beer–Lambert–Bouguer law. The accuracy of
such approximation significantly depends not only on the camera sensitivities
but also on its color calibration parameters. In this paper, we propose a
method for underwater images simulation, based on the banded spectral model,
which is devoid of the last drawback. In the proposed approach, the spectrum
of the registered radiance is estimated from the camera response and
attenuation modeling is performed in the spectral space. The average reproduction
angular error in simulation based on the banded spectral model is 20-30% less
than in channel-wise approximation. |
