Underwater imaging faces significant challenges, such as light attenuation, color distortion, and noise, which hinder the quality of captured images. This research aims to enhance underwater image quality by leveraging a hybrid approach based on deep learning models. The primary objective is to amalgamate convolutional neural networks (CNNs), generative adversarial networks (GANs), recurrent neural networks (RNNs), and deep reinforcement learning (DRL) to improve image quality, object detection, and classification in underwater environments. The methods employed involve integrating these advanced deep learning techniques to address the inherent challenges of underwater imaging. Experimental results demonstrate that the GAN-based approach outperforms others, achieving a PSNR value of 29.4 dB, compared to 27.8 dB for CNN, 28.1 dB for RNN, and 28.9 dB for DRL. These findings underscore the effectiveness of GANs in tackling underwater imaging issues, leading to significant advancements in image quality enhancement. This study contributes to the broader understanding of domain adaptation techniques and emerging technologies in underwater exploration. Future work will focus on optimizing hybrid designs, exploring novel deep learning strategies, and integrating advanced sensor technologies for real-time underwater imaging and exploration. Collaboration with domain experts will be crucial for validating these approaches in real-world underwater scenarios, advancing scientific discovery, environmental monitoring, and sustainable resource management.
