A Linear Programming Approach for Optimal Contrast-Tone Mapping

  title={A Linear Programming Approach for Optimal Contrast-Tone Mapping},
  author={Xiaolin Wu},
  journal={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 artifacts. The underlying contrast-tone optimization problem can be solved efficiently by linear programming. This new constrained… CONTINUE READING
