Meenakshi Chandel, Ruchika Sharma · 2014
This paper proposes an efficient analysis of MRI Image Denoising using different type of filtering methods. The search for efficient image denoising methods is still a valid challenge at the crossing of functional analysis and statistics. Image denoising has become an essential exercise in medical imaging especially the MRI image. This paper proposes a medical image denoising algorithm using Wiener and Median filter. The presence of noise in biomedical images is a major challenge in image processing and analysis. Denoising techniques are aimed at removing noise or distortion from images while retaining the original quality of the image. These images have been converted into grayscale and three types of noises have been added, including Speckle, Gaussians, and Salt & Pepper. In brief, this project succeeds to explore a new thresholding method with better performance in both PSNR and MSE. It reveals that median filter is the best filtering method to remove the Speckle, Gaussians, and Salt & Pepper noise. But in this paper we also used the different type of the Shrinks for the best result. For the implementation of this proposed work we use the Image Processing Toolbox under Matlab Software.
