This paper provides a hybrid method for underwater image restoration. Firstly, for the color distortion caused by different light attenuation characteristics, the automatic color balance algorithm which based on dynamic threshold is used to correct the color of underwater images. Secondly, the image dehazing based on the dark primary color principle is adopted, which transmissivity and background light are modified according to the propagation characteristics of underwater light. Finally, aiming at the over exposure of underwater images after dehazing, the gray world light compensation algorithm is employed to improve the visual display of underwater images. Experiments have shown the effectiveness of the system designed in this paper.
