Abstract

This paper proposes an algorithm which enhances the contrast of an input image using inter-pixel contextual information. The algorithm uses a two-dimensional (2D) histogram of the input image constructed using mutual relationship between each pixel and its neighbouring pixels. A smooth 2D target histogram is obtained by minimizing the sum of Frobenius norms of the differences from the input histogram, and the uniformly distributed histogram. The enhancement is achieved by mapping the
diagonal elements of the input histogram to the diagonal elements of the target histogram. Experimental results show that the algorithm produces better or comparable enhanced images than four state-of-the-art algorithms.
