[PDF] Nonlinear anisotropic filtering of MRI data ...
In contrast to acquisition-based noise reduction methods a postprocess based on anisotropic diffusion is proposed. Extensions of this technique support 3-D and multiecho magnetic resonance imaging (MRI), incorporating higher spatial and spectral dimensions. The procedure overcomes the major drawbacks of conventional filter methods, namely the blurring of object boundaries and the suppression ......
Performance Evaluation of Gabor Filter in ... - SpringerLink
Magnetic Resonance images are contaminated by Rician distributed noise due to the presence of contrast-diminishing signal-dependent bias. In this paper, Gabor filter approach for bias removal in MR...
 Fundamental Filters Performances Based on Window Sizes for ...
Abstract—In magnetic resonance imaging (MRI) images, noise is a common issue and it is locally signal dependent. Theoretical ... image by using Wave Atom Shrinkage [15] to overcome the problem of magnetic resonance (MR) ... filter and wavelet transformation based on noise reduction and reconstruction tools. The results have...
