Abstract

This paper proposed a digital image watermarking scheme based on Curvelet transform.Wrapping of specially selected Fourier samples is employed to implement Fast Discrete Curvelet Transform to transform the digital image to curvelet domain.First

use Arnold transform to encrypt the watermark.Then

repeat the cryptographic code many times to form a new code to creat the redundant data.Fianally

the proper position to embed the mark are chosen accoding to the characteristic of curvelet coefficients.The experiment results show that the scheme is robust to common image processing including JPEG compression

adding nosie

cut

Gaussion lowpass filter

Brighter Filter

Darker Filter

Increase/Decrease Contrast.Also the scheme has good invisibility.
