  abstract =     "With the rapid technological advancement in the
                 development, storage and transmission of digital
                 content, watermarking applications are both growing in
                 number and becoming complex. This has prompted the use
                 of computational intelligence in watermarking,
                 especially for thwarting attacks. In this context, we
                 describe the development of a new watermarking system
                 based on intelligent perceptual shaping of a digital
                 watermark using Genetic Programming (GP). The proposed
                 approach uses optimum embedding strength together with
                 appropriate DCT position selection and information
                 pertaining to conceivable attack in order to achieve
                 superior tradeoff in terms of the two conflicting
                 properties in digital watermarking, namely, robustness
                 and imperceptibility. This tradeoff is achieved by
                 developing superior perceptual shaping functions using
                 GP, which learn the content of a cover image by
                 exploiting the sensitivities/insensitivities of Human
                 Visual System (HVS) as well as attack information. The
                 improvement in imperceptibility and bit correct ratio
                 after attack are employed as the multi-objective
                 fitness criteria in the GP search.",
