Magetic resonance image enhancement based on multiscale Retinex algorithm

Abstract

Medical images, such as magnetic resonance (MR) images are crucial in clinical diagnosis. However, MR images always suffer from poor contrast due to imaging techniques. Therefore, an image enhancement approach based on multi-scale Retinex is presented in this paper. A set of MR images which show coronal slices are employed as testing samples. The experiments results demonstrated that the approach gains good performance and is simple and efficient in application.
