| Abstract | ||
| Contrast enhancement is a method to expand the contrast of features of interest so that they occupy a larger portion of the displayed gray level range without distortion to other features and the overall image quality. The problem in medical images is how to process and analyze of images (because it is important in medical diagnosis field) so that high quality information can be produced for satisfy disease and treatment. To produce a contrast enhancement recover an image within a given area darkness, also improve visual quality of it. In this paper we proposed a method of contrast enhancement which consists of two steps unsharp masking step and contrast enhancement step then bring out hidden details. We provide experimental results using different kind of medical images, which are hard to be contrasted by other conventional techniques.The output images show a wide variety of features, visible and interpretable to the human eye. Many more details become visible. The resulting images after applying the new proposed contrast are enhanced. | ||
