Adaptive fusion based deep learning framework for restoring underwater image quality using multi scale attention features
This paper proposes an Efficient Restoration of Underwater Images Using Multi-Scale Attention Features (ERUI-MSAF) model. It aims to restore underwater images by improving visibility and overall quality. The model employs adaptive bilateral filtering (ABF) for pre-processing to reduce noise and preserve edges. For image restoration, ERUI-MSAF integrates channel and spatial attention features to emphasize informative regions adaptively. It leverages Deep WaveNet (DWN) for spatial attention and EfficientNet for channel features, ensuring high performance and computational efficiency. Evaluations on EUVP and UIEB datasets show superior PSNR values of 34.258 and 29.0073 compared to existing models, highlighting its effectiveness in enhancing image quality, clarity, and contrast.
