Abstract: In digital image enhancement, contrast enhancement plays an important role. The main objective of contrast enhancement is to correct the local contrast in different area of the image. So that the feature unseen in the dark or bright area is brought out and exposed to the human views. In this paper improve the brightness of the dimmed images and preservation of image feature via multilevel thresholding, gamma correction and probability based entropy. The proposed method preserves the feature of the image and brightness and also improves image quality

Keywords: Contrast Enhancement, Gamma correction, Entropy, Multilevel thresholding
