The Rician noise in Magnetic Resonance Image (MRI) degrades the image quality and thus, accuracy in segmentation is reduced and localization of tumour may not be precise. In this article, a robust approach is proposed which estimates and removes the Rician noise of 2D MRI for improving segmentation...
