Abstract

The important feature of de-noising medical images is to reduce various types of noises namely, Impulse, Gaussian and Speckle noise which are normally found in medical imagery. Technological enhancement has considerably improved for de-noising medical images. This article proposes a comparative study on the various hybrid filters for the de-noise of Gaussian, impulse and Speckle from MRI, CT and ultrasound images respectively. The quality of the improved images is obtained by the statistical quantity measures: RMSE and PSNR values. This comparative study will give a good direction for selecting an appropriate filter in de-noising of medical images.
