A comparative study of image Steganography in the
wavelet domain and Curvelet domain using different
embedding techniques has been successful. The embedding
techniques used have their own applications and importance in
terms of what characteristics of image Steganography are
122
desired. The simulations are performed in Matlab
7.7.0(R2008b) and PSNR are calculated. It is found that
Curvelet is a better approach than wavelet transformation.
