Abstract
In this paper, a new watermark algorithm that based on wavelet packet transform is proposed for the watermark of remote sensing images, which include many high frequency components. The proposed watermark algorithm is used in the high frequency component of image and applies watermark to the overall subband that include the lowest frequency band. And the watermark is embedded on original image after selecting the significant wavelet packet coefficient. For selecting significant coefficients that apply watermark, zerotree is applied to packet transform using CPSO (Coefficient Partitioning Scanning Order) for imperceptibly and robustness. From the experimental result, the proposed algorithm shows better invisibility and robustness performance compare with conventional watermark methods. Especially, it demonstrates better robustness for high image compression in the remote sensing images application.
