Image Digital Watermarking Algorithm Based on Arnold Scrambling and Wavelet Transform

摘要：

A new image digital watermarking algorithm based on DWT is proposed, by which Arnold scrambling is firstly processed followed by wavelet decomposition in images. Then the watermark information is embedded in the processed digital images according to certain rules. The experimental results show that the algorithm has a better robustness against common attacks of JPEG and median filtering.
