A Robust Image Watermarking Algorithm Based on PCA and NN

Abstract:

In this paper, a novel gray-level image watermarking algorithm is presented for copyright protection. A method which encodes the gray-level secret information into bit sequence is developed. It uses the principal component analysis to extract the most valuable features of the watermark image and reduces lots of redundant information. The application of the proposed scheme makes the gray-level watermark capable of transparent hiding. Simulation results show that our method performs better than traditional methods.
