Abstract:

In this paper, a novel rectifier method is presented for improving and recovering underwater image quality. The suggested approach combines red channel optimization, levelling of contrast, and colour adjustment. The values of the R, G, and B channels are updated to provide comparable histogram distributions in order to address the problem of colour shift. Instead of fine-tuning the transmittance using dark channel prior-based restoration, the best transmittance is determined utilising a normalisation of contrast technique. To further enhance brightness and contrast, a red channel optimization technique based on redlight propagation is used. The usefulness of the suggested strategy in comparison to other wellliked techniques is highlighted by experimental results that show a significant improvement in both subjective visual effect and objective evaluation .
