摘要：Watermarking using genetic algorithm for the optimization of the tread-off between the watermarking requirements has attacked the attention of researchers; amongst the watermarking requirements, the imperceptibility and robustness is the main requirements. Watermarking embedded in frequency domain using DWT or DCT can affect the imperceptibility and robustness of watermarking, this paper studies the effect of embedding domain on the imperceptibility and robustness in genetic watermarking. Results of watermark image quality and attacks based on peak signal-to-noise ratio (PSNR) numerical correlation (NC) is analyzed through the paper sections, the DWT results showed more robustness high imperceptibility than DCT in watermarking based on GA.
