Abstract
In this paper, primarily Contrast Limited Adaptive Histogram Equalization (CLAHE) technique is used to boost the visibility of local details of low contrast image by improving the contrast of its local regions. Next, wiener filter is used as smoothing filter. Then it is followed by contrast stretching which is used for adjusting the contrast of the image. Finally, unsharp filtering is used to sharpen the obtained image. This yields enhanced image which is useful for diagnosis.
