AbstractIn this paper, we propose a novel digital watermarking technique based on neural networks for color images. Ourtechnique hides an invisible watermark into a color image, and then e!ectively cooperates neural networks to learn thecharacteristics of the embedded watermark related to the watermarked image. Due to neural networks possessingthe learning and adaptive capabilities, the trained neural networks almost exactly recover the watermark from thewatermarked image against image processing attacks. Extensive experimental results illustrate that our techniquesignicantly possesses robustness to be immune against the attacks. 2001 Elsevier Science B.V. All rights reserved.
