Abstract :
A new blind image watermarking scheme was proposed based on fast ICA and the wavelet tree structure, 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 JPEG compression, noise adding, cropping and so on.
