Red Preserving Algorithm for Underwater Imaging
The Gray World algorithm can remove the green or blue cast in underwater images. However, when one component of RGB is very little, it would lead to supersaturate and color distortion. In this paper, an improved Gray World algorithm, called Red Preserving is proposed. The minimum color component has been least changed, and the green or blue cast in the underwater images is suppressed. Experiments show that the proposed algorithm is simple and efficient. Compared to the classic Gray World algorithm, it can better suppress the cast and restore the images.
