We propose an image color correction algorithm based on a double transmission underwater imaging model to solve the color distortion problem associated with the underwater images. First, we divide the transmission as direct component transmission and backscatter component transmission based on the underwater imaging model. Subsequently, the backscatter component transmission is obtained by a red-dark channel prior, the background light is accurately estimated, and the direct component transmission of three channels is obtained based on the non-degenerate pixel points. Finally, both the transmissions are inserted into the imaging model to obtain the restored image. The experimental results demonstrate that the proposed algorithm can effectively remove the color cast of underwater images by relying only on the physical model.
