FPGA Implementation of Removal of Impulse Noise in Images by using MDBUT Technique
A novel idea of using median deviation parameter in estimating the noise in the images is proposed and successfully applied to gray level images. The median filter which is very popular in removing the salt and pepper noise from the images has undergone many changes in recent past. To this modified median filter the concept of mean deviation is added and used in estimating and removing the noise. The proposed method is implemented by developing a Graphical User Interface in MATLAB and also implemented using the Spartan 3E Filed Programmable Device. The results are found to be better than earlier methods and also robust in terms of preserving the contrast and fine details of the image even at high noise densities.
