Acquiring Spectral Scattering Properties of Seawater from an RGB Image

For accurate color restoration of underwater images, it is necessary to acquire the spectral scattering properties of seawater. In this study, we propose a method for acquiring spectral scattering properties from an RGB image. In the proposed method, we first obtain scattering properties (scattering and extinction coefficients) in RGB space. Then, we estimate spectral scattering properties from these RGB coefficients. We conduct simulation experiments using seawater datasets with various spectral scattering properties, and evaluate the accuracy of the proposed method.
