  abstract =     "we present a method for developing a Genetic
                 Perceptual Model (GPM) applicable to a watermarking
                 system. The proposed technique exploits the
                 characteristics of human visual system using a Genetic
                 Programming (GP) approach. We employ a tradeoff between
                 watermark robustness and imperceptibility, as an
                 optimisation criterion in the GP search. The resultant
                 GPM is a combination of frequency, luminance
                 sensitivity and contrast masking, enabling us to shape
                 the watermark according to the cover image. Our
                 investigations have shown that the evolved GPM provides
                 maximum allowable imperceptible alterations to the
                 Discrete Cosine Transform coefficients of a cover
                 image. Comparative studies in terms of watermark
                 imperceptibility and bit correct ratio performance have
                 been carried out. The performance of the GPM has been
                 analysed for various watermarking schemes.",
