  abstract =     "This paper presents a novel approach of adaptive
                 visual tuning of a watermark in Discrete Cosine
                 Transform (DCT) domain. The proposed approach
                 intelligently selects appropriate frequency bands as
                 well as optimal strength of alteration. Genetic
                 Programming (GP) is applied to structure the watermark
                 by exploiting both the characteristics of human visual
                 system and information pertaining to a cascade of
                 conceivable attacks. The developed visual tuning
                 expressions are dependent on frequency and luminance
                 sensitivities, and contrast masking. To further enhance
                 robustness, spread spectrum based watermarking and
                 Bose-Chadhuri-Hocquenghem (BCH) coding is employed. The
                 combination of spread spectrum sequence, BCH coding and
                 GP based non-linear structuring makes it extremely
                 difficult for an attacker to gain information about the
                 secret knowledge of the watermarking system.
                 Experimental results show the superiority of the
                 proposed approach against the existing approaches.
                 Especially, the margin of improvement in robustness
                 will be of high importance in medical and context aware
                 related applications of watermarking.",
