The Effect of Implementing of Nonlinear Filters for Enhancing Medical Images Using MATLAB

Abstract

Although this huge development in medical imaging tools, we find that there are some human mistakes in the process of filming medical images, where some errors result in distortions in the image and change some medical image properties which affect thedisease diagnosis correctly.Medical images are one of the fundamental images, because they are used in the most sensitive field which is a medical field. The objective of the study is to identify the effect of implement non-linear filters in enhancingmedical images, using the strongest and most popular program MATLAB, and because of its advantages in image processing. After implementation the researcher concluded that we will get the best result for medical image enhancement by using median filter which is one of the non-linear filters,non-linear filters implemented using Matlab functions.
