IMPLEMENTASI PENGURANGAN NOISE PADA CITRA TULANG MENGGUNAKAN METODE MEDIAN FILTER DAN GAUSSIAN FILTER

Abstract

The image that we have often decreases quality or quality, because it contains defects or is affected by noise. The color is less contrast, less sharp, blurry and so on. In such conditions image improvement is needed. The aim is to get an image display with a better form of visualization. Many techniques or methods used in image repair, among others, using the Median Filtering and Gaussian Filtering method. Of the several methods of repairing the image has advantages and disadvantages of each. The image will be tested given a Gaussian noise on the x-ray image, then analyzed its performance quantitatively. In this study a measurement process will be carried out in reducing noise in the image carried out by the Peak Signal-to-Noise Ratio (PSNR) method that is carried out during the filtering process.
