Summary:
In this paper, we propose an arrangement and detection method of an invisible calibration pattern based on human visual perception. The most important part of human visual perception in the proposed method is the spectral luminous efficiency characteristic and the chromatic spatial frequency characteristic. We embed the calibration pattern in an original image by adding high frequency component to blue intensity in a limited region. It is suggest that the proposed method protect page layout and artwork. Moreover, the proposed calibration pattern protects page layout and artwork.
