Abstract
Similar to other wavelet-based image processing algorithms, the choice of wavelet filters generally affects the performance of a wavelet-based watermarking system. Reported is an evaluation of a set of biorthogonal integer wavelets under a multiresolution-watermarking framework. Further investigation is conducted to justify the robustness performance against attacks.
