Color restoration method for underwater objects based on multispectral images

Perceiving color in water medium is always challenging due to the dense non-uniform attenuation and scattering of light across the visible spectrum. This paper presents a color restoration method for underwater objects based on multispectral images. To begin with, underwater multispectral images are obtained and restored with the influence of attenuation and scattering being eliminated by an in-suit restoration algorithm, and later on color images are restored from the multispectral images. Assessment of the restored color images and images taken by color camera in air medium authenticates the accuracy of the restoration method.
