Executive Summary

A new digital watermarking algorithm for color images based on Integer Wavelet Packet Transform and Feed Forward RBF (Radial Basis Function) Neural Network was proposed in this paper. Currently, there are some shortcomings such as weak resistance on the intentional attacks of geometric distortion and noise in some digital watermarking algorithm. Now the authors are introducing an approach using IWPT, as it yields a representation which is lossless, as it maps an integer-valued sequence onto integer-valued coefficients in the transformed domain.
