Comparative Analysis of Bilateral Filter and its Variants for Magnetic Resonance Imaging
Abstract
Background:
With the increase in research in the direction of making images noise free a number of algorithms have been designed.
Methods:
The choice of Denoising method will be made in such a way that it reduces or removes noise content on one hand and on the other hand it preserves the information content of the image. Our article focuses on analyzing the performance of bilateral filters and its derivatives for Denoising of MRI images.
Results:
The bilateral filter is a hybridized version of basic range filtering and domain filtering techniques.
Conclusion:
A comparative review of these filters is presented for MRI images taking different altitudes of Gaussian noise added to the image.
Keywords: Bilateral filter, Denoising, Domain Filtering, Noise types, Gaussian noise, MRI images.
