Underwater images are poor in contrast, so preprocessing techniques such as contrast enhancement is preferred to improve the image quality but when contrast enhancement was applied to a noisy image, it resulted in amplifying the noise artifacts. This article introduces a framework for enhancing underwater images using the particle swarm optimization algorithm a pre-processing step is introduced to reduce the absorbing and scattering effects of water before applying a filter based on this algorithm to enhance the image.
