%X Image segmentation is one of the important topic in digital image  processing which dividing image in each area intensity, so could be distinguish  between object and the background. The variety application of image  segmentation help human importance so much. One of it’s application is  upgrading the quality of medical image as pre-processing in order to make easier  for analized or interpreted through human visual means.    In this research there are three main process, among others is preprocessing,  processing,  dan  analysis.  Process  that  present  at  pre-processing  phase    are    sharpening, brightness, dan contrast. Processing phase was did by image  segmentation use otsu and iterative method. Whereas analysis phase was did by 3  comparison parameter, that is timing run, mean square error (MSE), and signal to  noise ratio (SNR). This research use 10 image sample from the various medical  image.   This research was did by image that through pre-processing and without  pre-processing. The experimental results on the image with pre-processing, that is  3 image compatible to use otsu and 7 image compatible to use iterative. The  experimental results on the image without pre-processing, that is 6 image  compatible to use otsu and 4 image compatible to use iterative.  Based on the  result, seen from comparison of the three parameter produce a great segmentation  method use pre-processing is iterative method, beside otsu method for without  using pre-processing.      Keywords : Medical image, Sharpening, Brightness, Contrast, Image  segmentation, Otsu method, Iterative method, Timing Run, MSE,  SNR
