Integrating Different Colour Spaces for Colour and Contrast Correction in Underwater Images

Abstract Underwater image processing has drawn a lot of interest in recent times since it is a crucial and demanding topic. Compared to the pictures taken in the air, underwater images are of lower quality and typically have a hazy, muted appearance. This study suggests a method for enhancing underwater images that makes use of both the RGB and LAB colour spaces basically focusing on two primary challenges essential for underwater image enhancement- colour and contrast distortion. These basic issues that underwater images face are addressed and handled using different colour spaces. The contrast can be increased using LAB colour space, and its hues can be restored using RGB colour channel. Experiments on underwater images shot in various conditions show that the recommended technique outperforms other cutting edge methods in terms of the final image quality.
