Description: A digital image watermarking scheme must be robust against a
variety of possible attacks. In the proposed approach, a new
rotation and scaling invariant image watermarking scheme is
proposed based on rotation invariant feature and image
normalization. The rotation invariant features are extracted
from the segmented areas and are selected as reference points.
Sub-regions centered at the feature points are used for
watermark embedding and extraction. Image normalization is
applied to the sub-regions to achieve scaling invariance. In the
scheme, first, the image is segmented into a number of
homogeneous regions and the feature points are extracted. Then
the circular regions for watermark embedding or extraction are
defined. Based on the image normalization and orientation
assignment, the rotation, scaling, and translation invariant
regions can be used for watermark embedding and extraction.
