An Optimal Image Watermarking Technology in DWT Domain
Junlong Wang · 2010
A DWT domain image watermarking scheme is proposed in this paper to meet the watermarking properties:security,imperceptibility and robustness.In the scheme,watermark comes from a meaningful binary image encrypted by two-dimensional chaotic stream encryption that has more security.In the procedure of watermark embedding,the watermark is embedded into host image through selecting and modifying the wavelet coefficients using Genetic algorithm with a simple fitness function to improve the imperceptibility of watermarked image.The results of our scheme realization and robust experiments show that this scheme has preferable performance.
