Abstract :
Multiwavelets have been used in image processing applications. They offer superior performance compared with scalar wavelets. This paper proposes a watermarking embedding and extraction techniques. It compares the performance of three multiwavelets and two scalar wavelets. The experiments compare the visibility requirement and robustness against some attacks. The experiments show that the multiwavelets outperform the scalar wavelets
