Abstract

Robustness and security are the key issues in the development of image watermarking algorithm. A new rotation invariant security image watermarking algorithm based on steerable pyramid transform is proposed in this paper. The algorithm is characterized as follows: (1) the rotation invariance and robust watermarking are achieved concurrently on the same transform domain; (2) the rotation synchronization is obtained through template matching by using steerable pyramid transform, which satisfies the shiftability in orientation condition; (3) the watermarks are embedded into an oriented subband at angle θ, which can be interpolated with base filter kernels and used as a key in watermark detection to increase the security of watermark; (4) the watermark detector is designed based on the steerable vector HMM model. High robustness is observed against StirMark attacks and their joint attacks.
