Blind watermarking algorithm based on wavelet tree and chaotic scrambling
|
Abstract:
A new blind image watermarking algorithm based on the wavelet tree structure was proposed, which featured the following characteristics as scrambling the watermark to enhance the security, taking advantage of the human visual system properties and extracting the watermark without original image. The experimental results show that the proposed blind image watermarking scheme is invisible and robust against various signal processing attacks such as compression, noise adding, image enhancement, cropping and so on.
