Image Contrast Enhancement Using Histogram Modification Framework
Journal Title: International Journal of Management, IT and Engineering - Year 2012, Vol 2, Issue 7
Abstract
The main objective of image enhancement is to improve some characteristic of an image to make it visually better one. A general framework based on histogram equalization for image contrast enhancement is presented. In this framework, contrast enhancement is posed as an optimization problem that minimizes a cost function. Histogram equalization is an effective technique for contrast enhancement. However, a conventional histogram equalization (HE) usually results in excessive contrast enhancement, which in turn gives the processed image an unnatural look and creates visual artefacts. By introducing specifically designed penalty terms, the level of contrast enhancement can be adjusted; noise robustness, white/black stretching and mean-brightness preservation may easily be incorporated into the optimization. Analytic solutions for some of the important criteria are presented.
