This book describes the design, development, and testing of a
novel digital watermarking technique for color images using Magic
Square and Ridgelet transforms. The novel feature of the method
is that it generates and uses multiple copies of the digital
watermark. The book describes how the method was tested for
embedding digital watermarks into color cover images, resulting
in very high PSNR value and yielding comparable results with
existing watermarking techniques.

To reach this new method, eight different techniques are
designed, developed and tested. First, the authors test two
digital watermarking techniques based on encryption: Image
Watermark Using Complete Complementary Code Technique (CCCT) and
Image Watermarking Using CCC-Fast Walsh Hadamard Transform
Technique (CCC-FWHTT).

Next, four digital watermarking techniques based on curvelet
transforms are discussed: Image Watermarking Using Curvelet
Transform (WCT), Watermark Wavelets in Curvelets of Cover Image
(WWCT), Resized Watermark into Curvelets of Cover Image (RWCT),
and Resized Watermark Wavelets into Curvelets of Cover
Image (RWWCT).

transforms are discussed: Image Watermarking Using Curvelet
Transform (WCT), Watermark Wavelets in Curvelets of Cover Image
(WWCT), Resized Watermark into Curvelets of Cover Image (RWCT),
and Resized Watermark Wavelets into Curvelets of Cover
Image (RWWCT).
Then, two final techniques are presented: Image Watermarking
Based on Magic Square (MST) and Image watermarking based on Magic
Square and Ridgelet Transform (MSRTT). Future research directions
are explored in the final chapter.

Designed for professionals and researchers in computer graphics
and imaging, Digital Watermarking Techniques in Curvelet and
Ridgelet Domain is also a useful tool for advanced-level
students.
