Medical image denoising based on improving K-SVD and block-matching 3D filtering

Abstract

Recently, the K-SVD algorithm has been widely used in the field of image denoising and has received state-of-the-art result. However, the K-SVD algorithm does not consider the self-similarity inherent in images. A novel algorithm for medical image noise reduction based on improving K-SVD and block-matching 3D filtering (BM3D) is derived in this paper… (More)
