Abstract
Most of the existing color image watermarking schemes were designed to mark the image luminance component only. Based on Quaternion Discrete Cosine Transform (QDCT), quaternion geometric Legendre moment invariants (QGLMIs) and least squares support vector machine (LS-SVM), we propose a robust color image watermarking in QDCT, which achieves high robustness and good visual quality. © 2012 Springer-Verlag.
