| description | The success of the Internet allows for the prevalent distribution of multimedia data
easily. Meanwhile, the ease of reproduction and distribution of digital documents create
problems for authorized parties that wish to prevent illegal use of such documents. To solve
this problem, a digital watermarking method for copyright protection is introduced. In this
dissertation, a color image watermarking system for copyright protection is proposed. A
visually recognizable watermark is used and embedded in the wavelet decomposition of the
color host image. The wavelet decomposition of host image used in this project is
Stationary Wavelet Transform (SWT) level 1 and level 2. In order to identify the suitable
channel of RGB color model for watermarking, three different channels of RGB color
model are tested by using different host images and watermarks. The experimental results
show that the proposed watermarking scheme is robust to Gaussian filtering, Gaussian
noise, salt and pepper noise, speckle noise and JPEG compression. |
