摘要：with the development in the digital imaging techniques, an image enhancement is one of the characteristic of image. The medical image enhancement is one of the application, these data can be suffer from some of the unnecessary noise, lack of contrast, sharpening and distort images due to these flaws we obtain false report for diagnosis of diseases. So for improving the quality of the medical image data various methodologies has been developed and proposed by different researchers. In this paper, we present literature of some of the techniques for enhancing the quality of medical digital image data and also describe their advantage and disadvantages.
