Dual Image Watermarking Algorithm Based on Block Truncation Code
Dual image watermarking algorithm based on block truncation
code is proposed. In the algorithm, after the origin image is
performed block truncation code and quad tree segmentation, the
area of HF image and LF image could be obtained. The HF and
LF image are decomposed using DWT. Moreover, the dual
watermarks are performed an m-sequence transformation. Select
LH coefficients and use SVD method. Embed the watermark into
V component of the SVD domain. The dual watermark image
can be got after the inverse SVD and DWT transformed. The
experimental results demonstrate that the watermarking
algorithm has good robustness against the attacks such as
rotation, image compression, noise addition, filtering and other
image processing actions.
