 Noise Reduction in Magnetic Resonance Images using Wave ...
This paper presents a de-noising method in Magnetic Resonance Images using Wave Atom Shrinkage that leads to the improvement of SNR in low and high noise level images. The paper is
Noise Reduction in Magnetic Resonance Images using Wave ...
It is well known that the noise in magnetic resonance imaging has a Rician distribution. Unlike additive Gaussian noise, Rician noise is signal dependent, and separating signal from noise is a difficult task. An efficient method for enhancement of noisy magnetic resonance image using wave atom shrinkage is proposed....

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....
Noise Removal in Magnetic Resonance Images using Hybrid ...
[1]. The de-noising of Magnetic Resonance Images using wave atom shrinkage is proposed in [2] and also proved that this approach achieves a better SNR compared to wavelet and curvelet shrinkages. A NL-Denoising method for Rician noise reduction is proposed in [3 & 4]. In [5], a test bed for baseline...
