 Rician Noise Reduction in MRI Images using Wave Atom Transform
in brain imaging. This paper presents an improved multi resolution de-noising method to de- noise Magnetic Resonance Images using Wave Atom Shrinkage , histogram based noise variance estimation [3] and modified threshold calculation that leads to the improvement of SNR in highnoise level images....
Evaluating Denoising Performances of Fundamental Filters ...
In Magnetic Resonance (MR) images, noise is a common issue which limits the image accuracy of any quantitative measurements. Noise elimination in MRI image pre-processing is an important step to eliminate the noise and to make the image fit for further steps involved in the process of analyzing....

Parameter Optimization for Local Polynomial Approximation ...
wave atom shrinkage for MRI images de-noising. The authors established that curvelet shrinkages were better than the wavelet method, as the proposed approach had achieved better SNR. Furthermore, the effectiveness of the proposed method was accentuated with large dataset of real-time normal and pathological MR images.
