Abstract
In this work, we present a generalized scheme for embedding watermark in digital images used for commercial aims. Genetic Programming is used to develop appropriate visual tuning functions, in accordance with Human Visual System, which cater for watermark imperceptibility-robustness trade off in the presence of a series of probable attacks. The use of low-density parity check codes for information encoding further enhances watermark robustness. Experimental results on a dataset of test images show marked improvement in robustness, when compared to the conventional approaches with the same level of visual quality. The proposed scheme is easy to implement and ensures significant robustness for watermarking a large number of small digital images.
