Channapragada Rama Seshagiri Rao,Munaga V.N.K. Prasad's Digital Watermarking Techniques in Curvelet and Ridgelet PDF

By Channapragada Rama Seshagiri Rao,Munaga V.N.K. Prasad

This publication describes the layout, improvement, and checking out of a unique electronic watermarking process for colour pictures utilizing Magic sq. and Ridgelet transforms. the unconventional characteristic of the strategy is that it generates and makes use of a number of copies of the electronic watermark.  The publication describes how the tactic used to be established for embedding electronic watermarks into colour hide photos, leading to very excessive PSNR worth and yielding similar effects with latest watermarking techniques.
To achieve this new process, 8 assorted thoughts are designed, built and confirmed. First, the authors attempt electronic watermarking suggestions according to encryption: snapshot Watermark utilizing entire Complementary Code process (CCCT) and picture Watermarking utilizing CCC-Fast Walsh Hadamard remodel process (CCC-FWHTT). 
Next, 4 electronic watermarking strategies according to curvelet transforms are mentioned: photo Watermarking utilizing Curvelet rework (WCT), Watermark Wavelets in Curvelets of canopy snapshot (WWCT), Resized Watermark into Curvelets of canopy picture (RWCT),  and Resized Watermark Wavelets into Curvelets of canopy snapshot (RWWCT). 
Then, ultimate ideas are offered: picture Watermarking in keeping with Magic sq. (MST) and photograph watermarking in line with Magic sq. and Ridgelet rework (MSRTT). destiny learn instructions are explored within the ultimate chapter.
Designed for pros and researchers in special effects and imaging, electronic Watermarking thoughts in Curvelet and Ridgelet area is usually a useful gizmo for advanced-level students.
