Abstract

This paper analyzes and compares the performance of different wavelet bases in the digital image watermarking and the effect of different wavelet decomposition series for the digital image watermarking embedding based on the application of wavelet in the digital image watermarking. The experiments proved the digital image watermarking embedding based on biorthogonal wavelet better than others, and summed up that too much or too little decomposition series would not good for conducting digital image watermarking embedding, the suitable decomposition series should be selected which based on cover image and digital watermark image.
