Abstract :
This paper presents a new digital image watermark algorithm, which based on the second generation wavelet. The algorithm decomposes the host image by multi-resolution wavelet firstly, and then embeds watermark into low frequency part with wavelet transformation, and meanwhile embeds watermark into intermediate frequency part with threshold method. This algorithm has good robustness under some conventional attacks and geometrical attacks. Also it is robust with static image compression.
