In the realm of image denoising, achieving optimal results heavily relies on the effective use of image priors. Traditional learning-based methods for developing these priors necessitate a vast collection of images for training purposes. Nevertheless, the practice visuals used in this technique don’t always have to match the particular noisy image that is being denoised, and it is frequently a computationally demanding procedure. This work presents a novel adaptive learning process aimed at producing more efficient picture patch priors in order to overcome these drawbacks. The adaptive Expectation–Maximization (EM) is a novel algorithm that converts a generic prior into a customized one based on the target image. EM adapting requires a substantially smaller amount of data to train than the normal EM technique. It is also more accessible and versatile because it may be used to pre-filtered photos even when clean images are not available. The study’s experimental findings show that the adapted priors created using adaptive EM continuously perform better than the unadapted before. Moreover, the proposed method exhibits superior performance in comparison with other denoising techniques already in use. This advancement signifies a substantial enhancement of face denoising, as the adapted priors not only enhance the quality of the denoised images but also reduce the dependency on extensive training datasets, thereby lowering computational costs and broadening the applicability of the method. Future research will enhance the EM adaptation algorithm by integrating deep learning techniques, extending it to handle noise, optimizing it for real-time applications, and exploring unsupervised or semi-supervised learning approaches.
