Rician noise removal on MRI using wave atom transform with ...
Abstract: Wave atom transform is a new multi-resolution technique, which has the ability to adapt to arbitrary local directions of a pattern, and to sparsely represent anisotropic patterns aligned with the axes. In this paper, a de-noising technique is proposed to remove the rician noise from Magnetic Resonance Images using wave atom shrinkage....
 MRI Denoising Using Waveatom Shrinkage
MRI Denoising Using Waveatom Shrinkage By Geetika Dua & Varun Raj ECE Deptt., GGSIPU Delhi Abstract - It is well known that noise in Magnetic Resonance Image has a Rician distribution. Unlike additive Gaussian noise, Rician noise is signal dependent, and separating signal from noise is a difficult task....

Performance Analysis for MRI Denoising using Intensity ...
The using wave atom shrinkage methodology for de-noising of Magnetic Resonance Images is proposed in [3] and also proved that this method fives a better SNR compared to wavelet and curvelet shrinkages. Rician noise can be reduced by a NL-Denoising method, proposed in [4 & 5].In [6],Total...
