Abstract: In this paper, a new robust digital image watermarking algorithm is proposed in
Directionlet transform domain. Directionlet transform (DT) is able to capture the directional
edges and contours superior to many multi-resolution geometric analysis (MGA) tools. At first,
sample the original image with the generator matrix; Then, decompose each coset into the
subbands with directionlet transform. For embedding watermark bits, We select a M×M
coefficients from the middle frequency domain of all the cosets of the lattice, as many as bits of
the binary watermark image. The experimental results show that the proposed algorithm has a
good resistance against to common attacks,moreover it outperforms previous methods in the
most situations. © 2012 IEEE.
