Effect of Frequency Domain Filters on Bio-Medical Images

Abstract

This study tries to find out the most effective frequency domain filter used for enhancing biomedical images. Five different biomedical images have been taken and they are filtered with different low and high pass filters at different cut off frequencies. As far as enhancement method is concerned, the method is very simple because the motive here is to find the most effective filter not a good enhancement technique. To assess the enhancement the metric MSE is used. The experiments are done on MATLAB.
