Abstract:
In medical image processing, medical images are polluted by different type of noises. Removing of noise from medical images is now a very tricky issue in the field of medical image processing. Most eminent noise reduction methods, which are usually based on the local statistics of a medical image, are not proficient for medical image noise reduction. This paper presents a competent and simple method for Rician noise reduction from MRI Brain image. The Proposed Gaussian filter is compared with other two image filtering algorithms. The eminence of the output images is measured by the statistical quantity measures: signal-to-noise ratio (SNR), peak signal-to-noise ratio (PSNR) and mean square error (MSE).
