A watermarking scheme based on slantlet transform, an orthogonal discrete
wavelet transform with two zero moments and with improved time localization, is
presented in this paper. The watermark is embedded into mid band frequencies of
slantlet coefficients in the transform domain, which leads to very small distortion
and guarantees the visual quality of the watermarked image. The performance of the
proposed algorithm is compared with embedding watermarking system using
wavelet transformation the result show promising performance of the proposed
system where the increasing in PSNR is approximately 20 dB.
