A Neutrosophic approach of MRI denoising

J Mohan, V Krishnaveni, Yanhui Guo
<span title="">2011</span> <i title="IEEE"> 2011 International Conference on Image Information Processing </i> &nbsp;
In this paper, a new filtering method to remove Rician noise from magnetic resonance image is presented. This filter is based on Neutrosophic set (NS) approach of median filtering.  ...  The γmedian filtering operation is used on T and F to decrease the set indeterminacy and remove noise. We have conducted experiments on real MR image with Rician noise added.  ...  ACKNOWLEDGMENT The authors would like to thank Sri Ramakrishna Imaging Center, Coimbatore for providing us the MRI data.  ...

In contrast to previous approaches, DTEMRL considers the joint distribution of all observed data in the context of an augmented tensor model to account for variable levels of Rician noise.  ...  Diffusion tensor imaging (DTI) is widely used to characterize white matter in health and disease.  ...  Current methods of computing tensors do not fully account for the physical noise structure in magnetic resonance (MR) data.  ...
