Detail-preserving denoising of CT and MRI images via adaptive clustering and non-local means algorithm

Abstract Medical imaging systems such as computed tomography (CT) and magnetic resonance imaging (MRI) are vital tools in clinical diagnosis and treatment planning. However, these modalities are inherently susceptible to Gaussian noise introduced during image acquisition, leading to degraded image q...
