| Abstract: | This paper presents a blind, still image, Genetic Programming (GP) based watermarking technique. The proposed technique embed appropriate level of watermark in the coefficients selected randomly in Morton order in 8*8 block size considering noise visibility function .Vertical and Horizontal sub-bands at second level of image is used for embedding purpose in wavelet domain. Noise Visibility Function (NVF) is used by the GP to intelligently determine the appropriate strength of watermark in the selected coefficients. Experimental results show that technique is quite robust against image processing attacks, noise attack, geometric attack and cascading attacks. |
