Journal ArticleDOI
Diffusion Weighted Image Denoising Using Overcomplete Local PCA
TL;DR: This new filter reduces random noise in multicomponent DWI by locally shrinking less significant Principal Components using an overcomplete approach and is compared with state-of-the-art methods using synthetic and real clinical MR images, showing improved performance in terms of denoising quality and estimation of diffusion parameters.
Journal ArticleDOI
New methods for MRI denoising based on sparseness and self-similarity.
TL;DR: Two new methods for the three-dimensional denoising of magnetic resonance images that exploit the sparseness and self-similarity properties of the images are proposed, making them usable in most clinical and research settings.
Journal ArticleDOI
Non-local MRI upsampling.
José V. Manjón,Pierrick Coupé,Antonio Buades,Vladimir S. Fonov,D. Louis Collins,Montserrat Robles +5 more
TL;DR: A new upsampling method is proposed to recover some of this high frequency information by using a data-adaptive patch-based reconstruction in combination with a subsampling coherence constraint to outperform classical interpolation methods in terms of quantitative measures and visual observation.
Journal ArticleDOI
MRI noise estimation and denoising using non-local PCA
TL;DR: A novel method for MRI denoising that exploits both the sparseness and self-similarity properties of the MR images by automatically estimating the local noise level present in the image and using it as a guide image within a rotationally invariant non-local means filter.
Journal ArticleDOI
MRI superresolution using self-similarity and image priors
TL;DR: A new superresolution method is proposed to reconstruct high-resolution images from the low-resolution ones using information from coplanar high resolution images acquired of the same subject.
