Title: | Example-based contrast enhancement for portrait photograph | Authors: | Chan, K. L. Zhang, Xiaoyan Constable, Martin |
Issue Date: | 2012 | Conference: | International Conference on Pattern Recognition (21st : 2012 : Tsukuba, Japan) | Abstract: | This paper proposes an approach whereby the regional contrasts in snap-shot style portrait photographs are enhanced using pre-modern portrait paintings as aesthetic exemplars. The reference portrait painting is selected based on a comparison of the existing contrast properties of the painting and the photograph. The contrast style in the selected reference painting is transferred to the photograph by mapping the inter-and intra-regional contrast of the regions, such as the face and skin area, reminder part of figure, and non-figure region. A novel two-part partial contrast stretching method is proposed to achieve the contrast mapping. Finally, the transition boundary between regions is smoothed and the non-figure region is blurred. The experiment results demonstrate the effectiveness of the proposed method. | URI: | https://hdl.handle.net/10356/99410 http://hdl.handle.net/10220/12889 |
