Tone mapping via edge-preserving total variation model

The purpose of tone mapping is making a high dynamic range image to be a low dynamic range image and to be displayed in the traditional monitors. Specifically, while a high dynamic range image is being compressed, its details must be preserved as many as possible without artifacts. At present, many tone mapping operators obtain good effects through combining edge-preserving filters with image decomposition. In this paper, we present a tone mapping operator based on an edge-preserving total variation model. We introduce the edge preservation of the total variation model and that how to do the tone mapping using it and the two-scale decomposition of a image. Finally, we demonstrate the effectiveness of our method by comparing it with four other tone mapping operators.
