N2 - Image contrast is an objective measure representing one of the distinct visual information. Although several contrast definitions are available in the literatures, most fail to match human perception. In this paper, we propose a no-reference objective contrast metric for complex images which follows the human visual perception. The contrast metric is obtained using the contrast perception depending image spatial frequency. Furthermore, the proposed contrast measurement includes integrating factors of human visual characteristics such as multi-scale property, contrast constancy property (supra-threshold region), color channel property and local adaptation property of the contrast sensitivity function (CSF).
