Image Denoising Using Python and Machine Learning

Abstract

Abstract: Image denoising is a fundamental task in image processing and computer vision, aimed at reducing noise while preserving important image details. Traditional denoising techniques often struggle to effectively remove noise while preserving fine details, especially in high-noise scenarios. In recent years, machine learning approaches have gained popularity for image denoising tasks, leveraging their ability to learn complex patterns and features directly from data. The denoising process begins with the acquisition of a noisy image, which is then preprocessed to enhance its features and reduce artifacts. The preprocessed image is fed into the trained deep learning model, which employs convolutional neural networks (CNNs) to learn the underlying noise patterns and predict the corresponding denoised image. The model is trained using a combination of loss functions, such as mean squared error (MSE) and perceptual loss, to optimize the denoising performance while preserving image details. To evaluate the proposed approach, extensive experiments are conducted on various benchmark datasets and compared against state-of-the-art denoising methods. Quantitative metrics, such as peak signalto-noise ratio (PSNR) and structural similarity index (SSIM), are used to measure the denoising performance. The results demonstrate that the proposed method outperforms existing techniques in terms of denoising quality, preserving fine details, and handling different noise types and levels.
