Abstract :
A new object-based watermarking scheme based on efficient self-similarity segmentation in the spatial domain is proposed. The lengths and orientation of two principal axes of the object were employed to achieve synchronizing detection problem. Experiments show the proposed method is robust to geometrical and cropped attacks.
