X-ray image plays a very important role in the medical identification. To help the doctors for diagnosis of the disease, some Transform for enhancing g X-ray images were proposed in the past decadesI mage enhancement is considered as one of the most important techniques in image research. . Many images like medical images, satellite, floating images and also real life photographs suffer from poor and bad contrast and noise. It is necessary to improve the contrast and eliminate the noise to increase image quality viewing, removing blurring and noise, increasing contrast, and revealing details. These are examples of enhancement operations. The enhancement technique differs from one field to another depending on its objective. The existing techniques of image enhancement can be classified into two categories: Spatial Domain and Transform Domain Enhancement. In this paper, we present an overview of Image Enhancement Processing Techniques in Transform Domain. More explicitly, we classifications processing methods based illustrative techniques of Image enhancement. Thus the contribution of this paper is to classify and review Image Enhancement Processing Techniques as well as Speckle noise has been applied to the image. Also we applied various transformation to identify which Transform is efficient in removing particular noises. This is identified by comparing the values obtained in PSNR and MSE values.
