Detection of Copies Using Mathematical Processing of Images I: Theoretical Basis and Methodology
 Blažek, Jan ; Hradilová, J. ; Zitová, Barbara ; Kamenický, Jan
We propose semi-automatic methods for registration and comparison digital images of fine art. Registration algorithm is based on estimation of perspective transformation parameters according to control points. Image comparison is based on statistical analysis of images, normalization of brightness and absolute deviation. Suitability of comparing algorithms is demonstrated on examples. As an output of comparing algorithms are used intelligible differential maps.
