Improving auto level method for enhancement of underwater images

The underwater images not only offer an interesting sight, but also have a challenge to monitor marine species and underwater activities. Taking a beautiful underwater image requires extraordinary equipment and technique. Usually, there are distorted colors on the image caused by poor light and water quality. So it requires an image enhancement process to get a proper photo to display. This research offers an improved method of auto levels to produce stunning photos. This method uses the color balancing based on the distribution of each channel R, G and B based on its histogram. The balancing of colors will reproduce colors more attractive compared with other methods of auto level.
