Comparative analysis of underwater images quality enhancement methods

Underwater imagery is one of the research areas of interest for marine exploration, such as environmental assessment, mineral detection and underwater living organisms analysis. For this research, clear, high-quality images of underwater objects are necessary. Underwater images, however, have always had visual, opaque, or excessive glare due to the lack of uniform and low light, which in turn results in the loss of detail in underwater images. On the other hand, the greater the depth of water, the more intense the light will diminish, which will result in the absorption of a series of wavelength by the water. This paper reviews, categorizes and compares the methods for enhancing underwater images. The results of this research show that color correction methods show better performance among other methods.
