Image Denoising in the Presense of High Level Salt and Pepper Noise using Modified Median Filter

In this paper, a Denoising algorithm is proposed to perform image denoising which eliminates salt and pepper noise. Several methods have been introduced to remove noise from digital images, such as Gaussian filtering, Mean filtering, Wiener filtering Wavelet thresholding etc.Many of these algorithms does not preserve fine details in the image while removing the noise. It is observed that the proposed method is better in suppressing salt and pepper noise at different noise levels than their counterparts.
