英文摘要	We propose a guided image contrast enhancement framework based on cloud images, in which the context-sensitive and context-free contrast is jointly improved via solving a multi-criteria optimization problem. In particular, the context-sensitive contrast is improved by performing advanced unsharp masking on the input and edge-preserving filtered images, while the context-free contrast enhancement is achieved by the sigmoid transfer mapping. To automatically determine the contrast enhancement level, the parameters in the optimization process are estimated by taking advantages of the retrieved images with similar content. For the purpose of automatically avoiding the involvement of low-quality retrieved images as the guidance, a recently developed no-reference image quality metric is adopted to rank the retrieved images from the cloud. The image complexity from the free-energy-based brain theory and the surface quality statistics in salient regions are collaboratively optimized to infer the parameters. Experimental results confirm that the proposed technique can efficiently create visually-pleasing enhanced images which are better than those produced by the classical techniques in both subjective and objective comparisons.; National High-Tech R&D Program of China, 863 Program [2015AA015903]; National Natural Science Foundation of China [61322106, 61571017, 61421062, 61300110]; Shenzhen Peacock Plan; SCI(E); EI; ARTICLE; sqwang1986@gmail.com; gukes.doctor@gmail.com; swma@pku.edu.cn; wslin@ntu.edu.sg; xmliu.hit@gmail.com; wgao@pku.edu.cn; 2; 219-232; 18
