A fourth order P_Laplace underwater image restoration method based on MSG

Underwater imaging system has been widely applied in varieties and it is desired to recover underwater image using image processing techniques. In this paper, we proposed a fourth order P_Laplace underwater image restoration method based on MSG. Although the fourth order P_Laplace method has been proved that it could effectively reduce the gradient effect, the bright spot effect and color distortion still exist in the restored image especially when iterations increase. However, MSG model can be applied to solve this issue. The structure image is restored by the fourth order P_Laplace approach to recover the detailed information embedded in the blurred structure image. Then the texture and the restored structure image are recomposed to output the recovered image.
