A Linear Programming Approach for Optimal Contrast-Tone Mapping

  • Xiaolin Wu
  • Published 2011 in IEEE Transactions on Image Processing


This paper proposes a novel algorithmic approach of image enhancement via optimal contrast-tone mapping. In a fundamental departure from the current practice of histogram equalization for contrast enhancement, the proposed approach maximizes expected contrast gain subject to an upper limit on tone distortion and optionally to other constraints that suppress… (More)
