Abstract

Contrast Enhancement plays an important role in digital image processing. It enables the human and automated perceiver to find out the less obvious information in the original image. Global Contrast Enhancement techniques are used in a wide range of applications to enhance the quality of an image. Local contrast enhancement also plays an important role for a detailed visibility of an image. In this paper we tried to enhance the contrast of an image using Global enhancement technique complemented with local image contrast enhancement methods. This paper proposes a method to obtain good contrast image based on its local and global information and by changing the gray values of pixels according to the objective gray scaled image.
