MEDICAL IMAGE DENOISING USING ADAPTIVE MEDIAN FILTERS

T he manipulation of an image has become necessary for the purpose of either extracting information from the image or for producing an alternative representation of the image. The noise is an issue that gets introduced while transferring images through all kinds of e lectronic communication. T he common noise in electronic communication is an impulse noise which is caused by un stable voltage. In this paper, the comparison of image denoising is discussed while applying it to the different medical images along with the calculation of various parameters before and after processing. The method will preserve the primary image details while suppressing the impulsive noise . This technique is being applied and analysed on various simulated images using MATLAB. However, the quantitave comparison is being done on the basis of calculation of PSNR, MSE, RMSE and Mean Absolute Error
