Underwater image enhancement algorithm based on RGB channels histogram equalization

In case of light absorption and diffusion, the clarity of the underwater images are degraded. The color of the underwater image is distortion. In order to improve the quality of the original underwater image quality, a method based on RGB channels histogram equalization is proposed. The method improves the contrast of the underwater image based on strength the histogram of the RGB channels respectively. The real-world experiment confirms the effectiveness of the method.
