In the field of image quality assessment, effective noise reduction is critical for enhancing the perceptual quality of images and improving the accuracy of subsequent analyses. This study proposes an enhancement to denoising autoencoders (DAEs) through optimization techniques aimed at significantly improving image quality assessment outcomes. Traditional DAEs, while effective in reconstructing clean images from noisy inputs, can sometimes fail to adequately preserve intricate image details and structures, which are essential for quality evaluation. Our approach incorporates optimization strategies, including adaptive learning rates, regularization techniques, and advanced loss functions, to refine the DAE architecture and improve its denoising capabilities. By training the enhanced model on diverse datasets containing various noise types and image content, we achieve superior performance in noise reduction. The effectiveness of the optimized denoising autoencoder is rigorously evaluated using standard image quality metrics, including Peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), and other perceptual quality measures. Results demonstrate a marked improvement in image quality, leading to more reliable assessments in various applications, including medical imaging, remote sensing, and multimedia content. This work highlights the potential of leveraging optimization techniques to enhance denoising autoencoders, thereby providing a robust solution for improving image quality assessment methodologies.
