：利用小波分块思想，结合Arnold 变换算法，提出了一种基于小波分块的水印算法，并且利用人类视觉系统的掩蔽特性，使

水印的不可感知性和鲁棒性得到很好的统一-: The use of wavelet blocks thinking, combined with Arnold transform algorithm, a block of the watermark based on wavelet algorithm, and using the masking properties of human visual system, making the watermark imperceptible and robust uniform well
